+## Column Naming Convention Samples
+
+The SnakeCaseNamingConvention applies these transformations:
+
+### Examples from BaseItems Table
+
+| Original (PascalCase) | Expected (snake_case) | SQL Has | Match? |
+|----------------------|----------------------|---------|--------|
+| Id | id | "Id" | ❌ |
+| IsMovie | is_movie | "IsMovie" | ❌ |
+| CommunityRating | community_rating | "CommunityRating" | ❌ |
+| DateCreated | date_created | "DateCreated" | ❌ |
+| IsVirtualItem | is_virtual_item | "IsVirtualItem" | ❌ |
+| PresentationUniqueKey | presentation_unique_key | "PresentationUniqueKey" | ❌ |
+| SeriesPresentationUniqueKey | series_presentation_unique_key | "SeriesPresentationUniqueKey" | ❌ |
+| PreferredMetadataLanguage | preferred_metadata_language | "PreferredMetadataLanguage" | ❌ |
+| TopParentId | top_parent_id | "TopParentId" | ❌ |
+
+**Conversion Rule (from SnakeCaseNamingConvention.cs):**
+```
+DateLastMediaAdded → date_last_media_added
+PreferredMetadataCountryCode → preferred_metadata_country_code
+InheritedParentalRatingSubValue → inherited_parental_rating_sub_value
+```

+
+## Impact Timeline
+
+### On Application Startup
+
+1. ✓ Database connection succeeds
+2. ✓ Migration history table found (`__EFMigrationsHistory`)
+3. ✓ Migrations complete
+4. ❌ First query to ActivityLog fails: `relation "activity_logs" does not exist`
+5. ❌ Application crashes
+
+### Error Messages You Will See
+
+```
+Npgsql.PostgresException: 42P01: relation "activity_logs" does not exist
+	at Npgsql.Internal.NpgsqlConnector.ReadMessageLong()
+	at [Your Entity Query Code]
+```
+
+### Affected Operations
+
+- ✓ Schema creation works (uses explicit table names in SQL)
+- ❌ Any LINQ query fails
+- ❌ Any repository method fails
+- ❌ Any DbContext.Set<T>.ToList() fails
+- ❌ Bulk operations fail
+- ❌ Migrations that query tables fail

+## Code Configuration References
+
+### PostgresDatabaseProvider.cs (Lines 763-823)
+Table mapping that creates the mismatch:
+```csharp
+public void OnModelCreating(ModelBuilder modelBuilder)
+{
+	modelBuilder.Entity<ActivityLog>().ToTable("activity_logs", Schemas.ActivityLog);
+	modelBuilder.Entity<ApiKey>().ToTable("api_keys", Schemas.Authentication);
+	// ... 31 mappings total ...
+}
+```
+
+### SnakeCaseNamingConvention.cs (Lines 25-30)
+Column name conversion that creates column mismatches:
+```csharp
+public void ProcessPropertyAdded(
+	IConventionPropertyBuilder propertyBuilder,
+	IConventionContext<IConventionPropertyBuilder> context)
+{
+	propertyBuilder.HasColumnName(ToSnakeCase(propertyBuilder.Metadata.Name));
+}

+# PostgreSQL Database Schema Mismatch Report
+
+**Generated:** 2025-05-01  
+**Status:** ⚠️ CRITICAL MISMATCH FOUND  
+**Severity:** HIGH - Code cannot query database tables correctly
+
+---
+
+## Executive Summary
+
+There is a **critical mismatch** between:
+1. **SQL Schema File** (`create_database_schema.sql`) - Uses **PascalCase** table and column names with double quotes
+2. **C# Code Configuration** (`PostgresDatabaseProvider.cs`) - Expects **snake_case** table names with SnakeCaseNamingConvention for columns
+
+This will cause **runtime failures** when EF Core tries to query tables that don't exist at the expected snake_case names.
+
+---
+
+## Detailed Mismatch Analysis
+
+### ACTIVITYLOG Schema
+
+#### SQL Definition:
+```sql
+CREATE TABLE activitylog."ActivityLogs" (
+	"Id" integer NOT NULL,
+	"Name" character varying(512) NOT NULL,
+	"Overview" character varying(512),
+	"ShortOverview" character varying(512),
+	"Type" character varying(256) NOT NULL,
+	"UserId" uuid NOT NULL,
+	"ItemId" character varying(256),
+	"DateCreated" timestamp with time zone NOT NULL,
+	"LogSeverity" integer NOT NULL,
+	"RowVersion" bigint NOT NULL
+);
+```
+
+#### C# Code Mapping:
+```csharp
+modelBuilder.Entity<ActivityLog>().ToTable("activity_logs", Schemas.ActivityLog);
+```
+
+#### Mismatch Details:
+| Aspect | SQL Schema | C# Code | Status |
+|--------|-----------|---------|--------|
+| Table Name | `"ActivityLogs"` | `activity_logs` | ❌ MISMATCH |
+| Column: Id | `"Id"` | `id` (via convention) | ❌ MISMATCH |
+| Column: Name | `"Name"` | `name` (via convention) | ❌ MISMATCH |
+| Column: Overview | `"Overview"` | `overview` (via convention) | ❌ MISMATCH |
+| Column: ShortOverview | `"ShortOverview"` | `short_overview` (via convention) | ❌ MISMATCH |
+| Column: Type | `"Type"` | `type` (via convention) | ❌ MISMATCH |
+| Column: UserId | `"UserId"` | `user_id` (via convention) | ❌ MISMATCH |
+| Column: ItemId | `"ItemId"` | `item_id` (via convention) | ❌ MISMATCH |
+| Column: DateCreated | `"DateCreated"` | `date_created` (via convention) | ❌ MISMATCH |
+| Column: LogSeverity | `"LogSeverity"` | `log_severity` (via convention) | ❌ MISMATCH |
+| Column: RowVersion | `"RowVersion"` | `row_version` (via convention) | ❌ MISMATCH |
+
+**Root Cause:** Table name is PascalCase; columns are PascalCase but SnakeCaseNamingConvention converts them to snake_case.

+
+## Impact Analysis
+
+### When EF Core Runs
+
+1. **Query Execution:** EF Core generates queries using snake_case table names
+   ```sql
+   SELECT * FROM library.base_items  -- EF Core generates this
+   ```
+
+2. **Database Response:** PostgreSQL looks for table named `base_items` in lowercase
+
+3. **Result:** Table not found because actual table is `"BaseItems"` (quoted PascalCase)
+   ```
+   ERROR: relation "base_items" does not exist
+   ```
+
+### Error Pattern You Will See
+
+```
+Npgsql.PostgresException (0x80004005): 42P01: relation "activity_logs" does not exist
+Npgsql.PostgresException (0x80004005): 42P01: relation "api_keys" does not exist
+Npgsql.PostgresException (0x80004005): 42P01: relation "base_items" does not exist
+```
+
+---
+
+## Root Cause Analysis
+
+### The Problem
+
+The SQL schema file was generated from a `pg_dump` of an existing database that uses **PascalCase with double quotes** for case preservation. However, the C# code was configured to map to **lowercase snake_case** table names.
+
+### Configuration Details
+
+**PostgresDatabaseProvider.cs Line 763-819:**
+```csharp
+public void OnModelCreating(ModelBuilder modelBuilder)
+{
+	// ... example mappings ...
+	modelBuilder.Entity<ActivityLog>().ToTable("activity_logs", Schemas.ActivityLog);
+	modelBuilder.Entity<ApiKey>().ToTable("api_keys", Schemas.Authentication);
+	modelBuilder.Entity<Device>().ToTable("devices", Schemas.Authentication);
+	// ... etc ...
+}
+```
+
+**PostgresDatabaseProvider.cs Line 872-875:**
+```csharp
+public void ConfigureConventions(ModelConfigurationBuilder configurationBuilder)
+{
+	configurationBuilder.Conventions.Add(_ => new SnakeCaseNamingConvention());
+}
+```
+
+**SnakeCaseNamingConvention.cs:**
+- Converts all PascalCase property names to snake_case column names
+- Example: `DateCreated` property → `date_created` column
+
+---
+
+## Recommended Resolution
+
+### Option 1: Update SQL Schema to Use Lowercase (RECOMMENDED)
+- **Pros:** Matches PostgreSQL best practices, cleaner, matches C# configuration
+- **Cons:** Requires recreating all tables
+- **Effort:** High (full database migration required)
+
+### Option 2: Update C# Code to Match PascalCase SQL
+- **Pros:** Quick fix, no database changes needed
+- **Cons:** Goes against PostgreSQL conventions, harder to maintain
+- **Effort:** Low (code changes only)
+
+### Option 3: Custom Naming Convention
+- Create a hybrid convention that recognizes existing PascalCase tables
+- **Pros:** Can work with existing database
+- **Cons:** Complex, non-standard, harder to maintain
+- **Effort:** Very High (custom infrastructure needed)
+

+## Files Affected
+
+### C# Code Files
+1. `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/PostgresDatabaseProvider.cs`
+   - Lines 763-823 (OnModelCreating table mappings)
+
+2. `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/SnakeCaseNamingConvention.cs`

+
+## Next Steps
+
+1. **Decision Required:** Which resolution option do you prefer?
+   - Option 1: Update SQL to lowercase (Recommended)
+   - Option 2: Update C# to PascalCase
+   - Option 3: Create custom convention
+
+2. **If Option 1:** Generate a comprehensive SQL migration script
+3. **If Option 2:** Generate C# code changes
+4. **If Option 3:** Design custom naming convention
+
+---
+
+## Appendix: Column Name Conversion Examples
+
+The SnakeCaseNamingConvention converts column names as follows:
+
+| Original (C#) | Converted (SQL) | Status |
+|---------------|-----------------|--------|
+| Id | id | ✓ |
+| UserId | user_id | ✓ |
+| DateCreated | date_created | ✓ |
+| LogSeverity | log_severity | ✓ |
+| AccessToken | access_token | ✓ |
+| APIKey | api_key | ✓ |
+| DVVersionMajor | dv_version_major | ✓ |
+
+**Note:** All column names in SQL schema are PascalCase (e.g., `"UserId"`, `"DateCreated"`), but C# code expects them in snake_case (e.g., `user_id`, `date_created`).

+# Dead Tuple Auto-Vacuum Guide
+
+## What was added
+
+The weekly PostgreSQL monitoring workflow now supports **conditional `VACUUM ANALYZE`** based on dead tuple thresholds.
+
+This was added to:
+
+- `scripts\Weekly-Performance-Monitor.ps1`
+- `scripts\Setup-Weekly-Monitor.ps1`
+
+When enabled, the monitor checks `pg_stat_user_tables` and runs:
+
+```sql
+VACUUM (ANALYZE, VERBOSE) schema.table_name;
+```
+
+only for tables that exceed both configured thresholds.
+
+## New monitor parameters
+
+`scripts\Weekly-Performance-Monitor.ps1` now supports:
+
+- `-AutoVacuumAnalyze`  
+  Enables conditional vacuum/analyze.
+- `-DeadTupleThreshold <int>`  
+  Minimum dead tuples required (default: `10000`).
+- `-DeadTuplePercentThreshold <double>`  
+  Minimum dead tuple percentage required (default: `20.0`).
+
+## How to run manually
+
+```powershell
+.\scripts\Weekly-Performance-Monitor.ps1 -AutoVacuumAnalyze
+```
+
+Example with custom thresholds:
+
+```powershell
+.\scripts\Weekly-Performance-Monitor.ps1 -AutoVacuumAnalyze -DeadTupleThreshold 15000 -DeadTuplePercentThreshold 25
+```
+
+## How to enable in the scheduled task
+
+`scripts\Setup-Weekly-Monitor.ps1` now supports:

+# EF Core Removal Analysis — pgsql-jellyfin Fork
+
+**Date**: 2025  
+**Scope**: Full codebase analysis of whether EF Core can and should be removed from this PostgreSQL-only fork.  
+**Verdict**: **Do not remove EF Core.** Address specific friction points instead.
+
+---
+
+## 1. Usage Inventory
+
+EF Core (`IDbContextFactory<JellyfinDbContext>`) is injected into **82 call sites across ~35 source files**, permeating every layer:
+
+| Layer | Files |
+|---|---|
+| API | `DatabaseViewsController` |
+| Repository (Item) | `BaseItemRepository`, `PeopleRepository`, `MediaStreamRepository`, `MediaAttachmentRepository`, `KeyframeRepository`, `ChapterRepository` |
+| Repository (Other) | `ActivityManager`, `DeviceManager`, `DisplayPreferencesManager`, `UserManager`, `TrickplayManager`, `MediaSegmentManager`, `AuthenticationManager`, `AuthorizationContext`, `LibraryOptionsRepository`, `BackupService` |
+| Scheduled Tasks | `PeopleValidationTask`, `CleanupUserDataTask`, `CleanDatabaseScheduledTask`, `UserDataManager` |
+| Migration Routines | 13 routines: `MigrateActivityLogDb`, `MigrateAuthenticationDb`, `MigrateDisplayPreferencesDb`, `MigrateKeyframeData`, `MigrateLibraryDb`, `MigrateLibraryUserData`, `MigrateRatingLevels`, `MoveExtractedFiles`, `RefreshCleanNames`, `RefreshInternalDateModified`, `FixDates`, `CleanMusicArtist`, (+ more) |
+| Infrastructure | `JellyfinMigrationService`, `PostgresDatabaseProvider`, `DbContextFactoryHealthCheck`, `Program.cs`, `ServiceCollectionExtensions` |
+
+The `JellyfinDbContext` itself defines **~35 DbSets** spanning 5 schemas (`activitylog`, `authentication`, `displaypreferences`, `library`, `users`).
+
+---
+
+## 2. Query Complexity — What EF Core Actually Does
+
+### 2.1 BaseItemRepository.cs — The Core Case
+
+`BaseItemRepository.cs` is **3,583 lines / 152 KB**, the largest file in the repository. It is the performance-critical code path for all library browsing, search, and playback-related queries. It is built entirely on EF Core LINQ.
+
+**Key EF-dependent sub-systems inside it:**
+
+| Method | EF Feature Used | Purpose |
+|---|---|---|
+| `TranslateQuery()` (lines 2548+, ~500 lines) | LINQ predicate composition over `IQueryable<BaseItemEntity>` | Translates `InternalItemsQuery` (60+ filter parameters) to SQL WHERE clauses |
+| `ApplyOrder()` (~80 lines) | `OrderBy` / `ThenBy` over EF expression trees, `OrderMapper.MapOrderByField()` | Translates `ItemSortBy` enum to typed SQL ORDER BY |
+| `ApplyNavigations()` | Conditional `Include()` / `ThenInclude()` | Eagerly loads TvExtras, AudioExtras, LiveTvExtras, Provider, Images, UserData per DTO field set |
+| `ApplyGroupingFilter()` | `DistinctBy()` → PostgreSQL `DISTINCT ON` | Deduplication for presentation unique keys |
+| `GetNextUpSeriesKeys()` | `Join()` + `GroupBy()` + `Max()` | Complex TV "next up" episode query |
+| `GetItemValues()` | Nested `Join()` + `SelectMany()` + correlated subquery pattern | Artist/Genre/Studio item-value lookups |
+| `UpdateOrInsertItemsAsync()` | `CreateExecutionStrategy().ExecuteAsync()`, `SaveChangesAsync()`, `Attach().State = EntityState.Modified`, `AddRange()` | Transactional batch upsert |
+| Entity state management | `context.Entry(placeholder).State = EntityState.Detached` | Upsert conflict resolution |
+| `EF.Constant()` | PostgreSQL-specific plan hint | Prevents parameterization of the placeholder UUID to allow index scans |
+
+**LINQ operator counts in BaseItemRepository.cs** (approximate from code review):  
+- `Where()`, `Select()`, `Join()`, `GroupBy()`, `Include()`, `ThenInclude()`, `OrderBy()`: **200+ call sites**  
+- `ExecuteDelete()` / `ExecuteUpdate()` bulk ops: **~25 call sites**  
+- `FromSqlRaw` / `FromSqlInterpolated`: **0** — reads are pure LINQ  
+- `ExecuteSqlAsync()` raw SQL upserts: **~8** (ON CONFLICT upserts for extension tables)
+
+The LINQ query composition is not superficial mapping sugar — `TranslateQuery` conditionally applies 30+ predicate branches (user data filters, rating filters, type filters, ancestor traversal, search term scoring, tag inheritance, etc.) based on `InternalItemsQuery` flags. This is the equivalent of a 500-line dynamic SQL builder, expressed in type-safe C#.
+
+### 2.2 Other Repositories
+
+The other repositories (`ActivityManager`, `UserManager`, `DeviceManager`, etc.) use EF more simply — primarily `Where()` + `Select()` + `SaveChanges()` patterns — but collectively represent hundreds more LINQ call sites.
+
+### 2.3 Hybrid Usage Already Present
+
+`BaseItemRepository.UpdateOrInsertItemsAsync()` already uses a hybrid approach: EF Core for reads and change-tracking, **raw `ExecuteSqlAsync()` for ON CONFLICT upserts**. This tells us the team is already reaching EF's limits on writes.
+
+---
+
+## 3. Migration Infrastructure
+
+### 3.1 EF Schema Migrations Are DISABLED
+
+Per `JellyfinMigrationService.cs` (line ~275):
+```csharp
+// DISABLED for .NET 11 preview: EF Core database migrations don't work with preview SDK
+// Database schema is initialized from SQL scripts in PostgresDatabaseProvider instead
+/*
+if (stage is JellyfinMigrationStageTypes.CoreInitialisation)
+{
+    pendingDatabaseMigrations = migrationsAssembly.Migrations...
+}
+*/
+```
+
+**EF's primary justification — schema migration management — is already bypassed.** Schema is initialized via `sql/schema_init/create_database_schema.sql` + `psql`.
+
+### 3.2 EF Is Still Used for Code Migration Tracking
+
+`JellyfinMigrationService` still uses EF to track *which code routines have run* via `__EFMigrationsHistory`:
+
+```csharp
+var historyRepository = dbContext.GetService<IHistoryRepository>();
+await historyRepository.CreateIfNotExistsAsync();
+var appliedMigrations = await dbContext.Database.GetAppliedMigrationsAsync();
+await dbContext.Database.ExecuteSqlRawAsync(
+    historyRepository.GetInsertScript(new HistoryRow(migrationId, version)));
+```
+
+This usage of `IHistoryRepository` is what required the `SnakeCaseHistoryRepository` workaround (custom class overriding `MigrationIdColumnName` and `ProductVersionColumnName`, using `#pragma warning disable EF1001` because the base class is internal EF infrastructure).
+
+---
+
+## 4. Known Friction Points
+
+These are the specific problems that prompted this analysis:
+
+### 4.1 Snake_case Naming Impedance (FIXED, but fragile)
+
+EF Core defaults to PascalCase. This fork uses snake_case PostgreSQL conventions. Three workarounds are required:
+
+1. **`SnakeCaseNamingConvention`** — `IPropertyAddedConvention` that converts all property names to snake_case at model build time  
+2. **`SnakeCaseHistoryRepository`** — custom `NpgsqlHistoryRepository` subclass overriding column name properties; requires `#pragma warning disable EF1001` (breaking internal EF API)  
+3. **Manual table names in model configurations** — 31 `IEntityTypeConfiguration` files; two (`LibraryOptionsEntityConfiguration`, `HomeSectionConfiguration`) had PascalCase table names that overrode the convention and caused `relation "library.LibraryOptions" does not exist` errors at runtime
+
+**Risk**: Every future upstream EF Core upgrade may break `SnakeCaseHistoryRepository` since it depends on internal EF infrastructure.
+
+### 4.2 Execution Strategy Transaction Friction (FIXED, but imposed on all writers)
+
+`EnableRetryOnFailure` in the PostgreSQL retry strategy makes EF Core incompatible with user-initiated `BeginTransaction()`. All transactional code must wrap in `context.Database.CreateExecutionStrategy().Execute(...)`. This has already been fixed in `MigrateRatingLevels` and `MigrateKeyframeData` but is an ongoing constraint.
+
+### 4.3 EF-PostgreSQL Translation Gaps
+
+Multiple code comments document EF Core translation failures:
+
+- `DistinctBy()` on complex types sometimes cannot be translated → fallback to `ApplyGroupingInMemory()` using **reflection on anonymous types**  
+- `GetItemValues()` in some paths falls back to `.AsEnumerable()` for in-memory filtering  
+- `GetLatestItemList()` had to be split into two queries to avoid untranslatable nested `Min()` subqueries  
+- A documented 165s query regression was caused by EF generating correlated subqueries — fixed by switching to `DistinctBy()` → `DISTINCT ON`  
+- `AsSingleQuery()` required explicitly to prevent N+1 for multi-table includes
+
+### 4.4 Inconsistent Table Naming in Raw SQL
+
+`UpdateOrInsertItemsAsync()` uses raw `ExecuteSqlAsync()` with PascalCase quoted names:
+
+```csharp
+$@"INSERT INTO library.""BaseItemProviders"" (""ItemId"", ""ProviderId"", ""ProviderValue"")..."
+$@"INSERT INTO library.""BaseItemTvExtras"" (""ItemId"", ..."
+```
+
+These PascalCase quoted names (`"BaseItemProviders"`, `"BaseItemTvExtras"`) are inconsistent with the snake_case goal of the fork. The actual table names in PostgreSQL must match these quoted strings exactly — implying the schema init SQL creates them with PascalCase quoted names, not the snake_case convention applied to EF properties.
+
+### 4.5 Known Performance Anti-Pattern in `GetItemValues`
+
+```csharp
+// TODO: This is bad refactor!
+itemCount = new ItemCounts() {
+    SeriesCount = itemCountQuery!.Count(f => f.Type == seriesTypeName),
+    EpisodeCount = itemCountQuery!.Count(f => f.Type == episodeTypeName),
+    // ... 5 more COUNT queries
+}
+```
+
+This executes 7 separate `COUNT` queries per item in a result set — a classic N+1 problem embedded in an EF projection. This is an EF translation limitation (aggregate counts in a nested `SELECT` project).
+
+---
+
+## 5. Can EF Core Be Removed?
+
+**Technically: Yes. Practically: The cost is prohibitive.**
+
+A full removal would require:
+
+1. **Rewriting `BaseItemRepository.cs`** (3,583 lines) as raw SQL — either Dapper or direct `NpgsqlCommand`. The `TranslateQuery` method alone is a ~500-line dynamic query builder that would need to be rewritten as a SQL string builder. All `Include()` chains would become explicit JOINs. All `ExecuteUpdate`/`ExecuteDelete` calls would become parameterized SQL.
+
+2. **Replacing 31 ModelConfiguration files** with SQL schema definitions (partially done via `sql/schema_init/`).
+
+3. **Replacing the migration tracking system** (`IHistoryRepository`) with a simple SQL table + custom tracker.
+
+4. **Rewriting all other repositories** (~15 files) as Dapper or raw Npgsql.
+
+5. **Replacing all `IDbContextFactory` injection points** (~35 files, 82 sites) with new connection/command factories.
+
+**Estimated effort: 3–6 person-months of careful rewrite, plus extensive testing coverage.**
+
+Alternatives assessed:
+
+| Alternative | Pros | Cons |
+|---|---|---|
+| **Full removal (Dapper + Npgsql)** | Full control of SQL; no EF friction; better PostgreSQL-native features | 3-6 month rewrite; no dynamic LINQ query composition; lose `ExecuteUpdate`/`ExecuteDelete`; high regression risk |
+| **Hybrid (EF reads, Dapper writes)** | Eliminates write friction; keeps LINQ query composition | Two persistence paradigms; still need EF for reads; does not eliminate snake_case friction |
+| **Keep EF, address friction points** | Minimal disruption; preserves LINQ query composition | Ongoing EF+PostgreSQL compatibility work; preview SDK risk |
+| **Replace only migration tracking** | Eliminates `SnakeCaseHistoryRepository` hack | Small gain; does not address execution strategy or translation friction |
+
+---
+
+## 6. Should EF Core Be Removed?
+
+**No — but specific friction points should be addressed deliberately.**
+
+### 6.1 Why EF Core Should Stay
+
+**The LINQ query composition in `TranslateQuery` / `ApplyOrder` is EF Core's core contribution to this codebase.** It provides:
+
+- **Type safety** across 60+ filter parameters in `InternalItemsQuery`
+- **Composability** — predicates are built incrementally, each branch independently testable
+- **Maintainability** — 500 lines of C# expression trees is significantly more maintainable than equivalent raw SQL string building
+- **`ExecuteUpdate`/`ExecuteDelete`** — these EF 7+ bulk operations map directly to `UPDATE ... WHERE` and `DELETE ... WHERE` without loading entities; replacing these with raw SQL would produce functionally identical code with more boilerplate
+- **Navigation property loading** (`Include`) — the conditional navigation loading in `ApplyNavigations` maps cleanly to the DTO field selection pattern used by the API layer
+
+EF Core's value in this codebase is almost entirely in the **read path** (LINQ-to-SQL translation) and **bulk operations** (`ExecuteUpdate`/`ExecuteDelete`). Its weaknesses are in the write path and infrastructure (migration history, naming conventions, execution strategy).
+
+### 6.2 Recommended Targeted Actions
+
+In priority order:
+
+#### Priority 1 — Replace Migration History Tracking (Low effort, high safety gain)
+
+The `SnakeCaseHistoryRepository` workaround depends on EF internal APIs (`#pragma warning disable EF1001`). Replace the code migration tracking with a simple dedicated table and Dapper/Npgsql:
+
+```sql
+CREATE TABLE IF NOT EXISTS public.jellyfin_applied_migrations (
+    migration_id VARCHAR(150) PRIMARY KEY,
+    applied_at TIMESTAMPTZ NOT NULL DEFAULT now(),
+    product_version VARCHAR(32) NOT NULL
+);
+```
+
+Remove `JellyfinMigrationService`'s dependency on `IHistoryRepository` and `GetAppliedMigrationsAsync()`. This eliminates the most fragile EF workaround.
+
+#### Priority 2 — Fix Raw SQL Table Names to Match snake_case Schema (Low effort, correctness)
+
+`UpdateOrInsertItemsAsync` uses `library."BaseItemProviders"`, `library."BaseItemTvExtras"`, etc. If the fork's goal is snake_case naming, verify whether these tables exist as quoted PascalCase or as snake_case in PostgreSQL, and make the raw SQL consistent. Quoted PascalCase in PostgreSQL is case-sensitive and is a footgun.
+
+#### Priority 3 — Replace Write Path with Raw SQL/Dapper (Medium effort, eliminates execution strategy friction)
+
+The `UpdateOrInsertItemsAsync` method is already a hybrid (raw SQL for ON CONFLICT upserts + EF for the surrounding logic). Converting the remaining EF write operations (`SaveChangesAsync`, `Attach().State = EntityState.Modified`, `AddRange()`) in this method to direct Npgsql/Dapper calls would:
+
+- Eliminate the `CreateExecutionStrategy().Execute()` wrappers
+- Enable direct PostgreSQL `ON CONFLICT DO UPDATE` throughout
+- Remove the impedance between EF change tracking and PostgreSQL's native upsert semantics
+
+**Do not extend this to reads** — the LINQ query composition is worth keeping.
+
+#### Priority 4 — Fix the N+1 in `GetItemValues` (Medium effort, performance)
+
+The 7 separate `COUNT` queries per item should be replaced with a single `GROUP BY type, COUNT(*)` query executed once and pivoted in memory. This is a correctness/performance issue independent of whether EF is removed.
+
+---
+
+## 7. Summary
+
+| Question | Answer |
+|---|---|
+| **Can EF Core be removed?** | Yes, technically. Estimated 3–6 person-months of work. |
+| **Should EF Core be removed?** | No. The LINQ query composition in `BaseItemRepository` is EF's core value and cost-prohibitive to replace. |
+| **Is EF Core being used optimally?** | No. The write path, migration tracking, and naming convention workarounds are sources of ongoing friction. |
+| **What should be done instead?** | Replace migration tracking with a native SQL table; convert the write path in `BaseItemRepository` to raw SQL; keep EF for the LINQ read path. |
+| **Biggest ongoing risk?** | `SnakeCaseHistoryRepository` uses internal EF APIs (`EF1001`) that may break on EF Core version bumps. Replacing migration tracking eliminates this. |
+| **Second biggest risk?** | EF Core + Npgsql preview packages (`11.0.0-preview.1`) on `net11.0`. Schema migrations are already disabled because of this. Pin to stable as soon as net11.0 releases. |

+# Library Options DB Design
+
+This document turns the earlier storage discussion into concrete PostgreSQL DDL and C# repository sketches that fit the patterns already used in this repository.
+
+Relevant existing patterns:
+
+- PostgreSQL migrations use `MigrationBuilder.Sql(...)` in provider-specific migrations under `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/`.
+- EF entities live under `src/Jellyfin.Database/Jellyfin.Database.Implementations/Entities/`.
+- `DbSet<>` registrations live in `src/Jellyfin.Database/Jellyfin.Database.Implementations/JellyfinDbContext.cs`.
+- PostgreSQL table mapping lives in `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/PostgresDatabaseProvider.cs`.
+- Runtime repositories typically use `IDbContextFactory<JellyfinDbContext>` and `await using var context = _dbProvider.CreateDbContext();` as seen in `Jellyfin.Server.Implementations/Item/MediaStreamRepository.cs`.
+- Virtual path storage is already handled by `IServerApplicationHost.ReverseVirtualPath(...)` and `ExpandVirtualPath(...)`.
+
+## Option 1: Minimal-Change JSON-In-DB
+
+### Goal
+
+Persist one `LibraryOptions` document per collection folder in PostgreSQL with minimal change to the existing `CollectionFolder.GetLibraryOptions(...)` and `SaveLibraryOptions(...)` flow.
+
+### Table Design
+
+```sql
+CREATE TABLE library."LibraryOptions" (
+    "LibraryId" uuid NOT NULL,
+    "LibraryPath" text NOT NULL,
+    "OptionsJson" jsonb NOT NULL,
+    "Version" integer NOT NULL DEFAULT 1,
+    "DateCreated" timestamp with time zone NOT NULL DEFAULT now(),
+    "DateModified" timestamp with time zone NOT NULL DEFAULT now(),
+    CONSTRAINT "PK_LibraryOptions" PRIMARY KEY ("LibraryId")
+);
+
+CREATE UNIQUE INDEX "IX_LibraryOptions_LibraryPath"

+```
+
+### CollectionFolder Integration Sketch
+
+The minimal integration strategy is:
+
+1. Change `CollectionFolder.LoadLibraryOptions(...)` to try the repository first.
+2. If no database row exists, fall back to `options.xml`.
+3. After a successful XML read, persist the value into `library."LibraryOptions"`.
+4. Keep the current static cache keyed by library path.
+
+Pseudo-flow:
+
+```csharp
+var fromDb = await _libraryOptionsRepository.GetLibraryOptionsAsync(libraryId, path, cancellationToken);
+if (fromDb is not null)
+{
+    return fromDb;
+}
+
+var fromXml = LoadLibraryOptionsFromXml(path);
+await _libraryOptionsRepository.SaveLibraryOptionsAsync(libraryId, path, fromXml, cancellationToken);
+return fromXml;
+```
+
+### Tradeoffs
+
+- Lowest risk.
+- No relational visibility into individual media roots.
+- Best fit if the goal is only to stop using `options.xml` as the persistence backend.
+
+## Option 2: Hybrid JSON + Queryable Media Paths
+
+### Goal
+
+Keep the full `LibraryOptions` object as JSON for compatibility, but project `PathInfos` into a separate relational table so path-level reporting and joins are cheap and reliable.
+
+### Table Design
+
+```sql
+CREATE TABLE library."LibraryOptions" (
+    "LibraryId" uuid NOT NULL,
+    "LibraryPath" text NOT NULL,
+    "OptionsJson" jsonb NOT NULL,
+    "Version" integer NOT NULL DEFAULT 1,
+    "DateCreated" timestamp with time zone NOT NULL DEFAULT now(),
+    "DateModified" timestamp with time zone NOT NULL DEFAULT now(),
+    CONSTRAINT "PK_LibraryOptions" PRIMARY KEY ("LibraryId")
+);
+
+CREATE UNIQUE INDEX "IX_LibraryOptions_LibraryPath"
+    ON library."LibraryOptions" USING btree ("LibraryPath");
+
+CREATE TABLE library."LibraryMediaPaths" (
+    "Id" uuid NOT NULL,
+    "LibraryId" uuid NOT NULL,

+    CONSTRAINT "FK_LibraryMediaPaths_LibraryOptions_LibraryId"
+        FOREIGN KEY ("LibraryId") REFERENCES library."LibraryOptions" ("LibraryId") ON DELETE CASCADE
+);
+
+CREATE UNIQUE INDEX "IX_LibraryMediaPaths_LibraryId_Position"
+    ON library."LibraryMediaPaths" USING btree ("LibraryId", "Position");
+
+CREATE INDEX "IX_LibraryMediaPaths_Path"
+    ON library."LibraryMediaPaths" USING btree ("Path");

+            .ConfigureAwait(false);
+    }

+```
+
+### Operational Queries Enabled By The Hybrid Model
+
+```sql
+SELECT lmp."LibraryId", lmp."Path", lmp."PathVirtual"
+FROM library."LibraryMediaPaths" AS lmp
+WHERE lmp."Path" = '/media/main_bridge/media/movies'
+   OR lmp."PathVirtual" = '/media/main_bridge/media/movies';
+```
+
+```sql
+SELECT lmp."Path", count(*) AS "LibraryCount"
+FROM library."LibraryMediaPaths" AS lmp
+GROUP BY lmp."Path"
+HAVING count(*) > 1
+ORDER BY "LibraryCount" DESC, lmp."Path";
+```
+
+### Tradeoffs
+
+- Slightly more implementation work than the JSON-only option.
+- Keeps the current `LibraryOptions` object model intact.
+- Makes media roots queryable, indexable, and auditable.
+- Requires a transactional write path so JSON and projected rows do not drift.
+
+## Recommended Touch Points In This Repo
+
+Regardless of which option is chosen, the same set of integration points will need to move:
+
+- `MediaBrowser.Controller/Entities/CollectionFolder.cs`
+  - Replace raw XML read/write with repository-backed read/write.
+  - Keep XML fallback for a transition period if rollback safety matters.
+- `src/Jellyfin.Database/Jellyfin.Database.Implementations/JellyfinDbContext.cs`
+  - Add `DbSet<>` properties.
+- `src/Jellyfin.Database/Jellyfin.Database.Implementations/Entities/`
+  - Add `LibraryOptionsEntity` and, for the hybrid approach, `LibraryMediaPathEntity`.
+- `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/PostgresDatabaseProvider.cs`
+  - Add table mapping and relationship/index configuration.
+- `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/`
+  - Add provider-specific migration(s).
+- `Jellyfin.Server.Implementations/Library/`
+  - Add a repository class and register it in DI.
+
+## Recommended Rollout
+
+### JSON-In-DB
+
+1. Add the table, entity, mapping, and repository.
+2. Read DB first, then fall back to XML.
+3. Backfill on demand when XML is encountered.
+4. Keep XML writes optional for one release if rollback support is needed.
+
+### Hybrid
+
+1. Add both tables, entities, mapping, and repository.
+2. Save JSON and `PathInfos` projection in one transaction.
+3. Read DB first, then fall back to XML.
+4. Add a small admin or diagnostic query surface over `LibraryMediaPaths`.
+5. Remove XML writes after migration confidence is high.
+
+## Recommendation
+
+If the immediate goal is only to stop relying on `options.xml`, choose the JSON-only design.
+
+If the goal includes operational visibility into library roots, duplicate path detection, path remapping support, or future query-driven tooling, choose the hybrid design. The hybrid design is the better long-term fit for PostgreSQL while still preserving the current `LibraryOptions` object graph and call sites.

+# Jellyfin with PostgreSQL Support
+
+This is a fork of Jellyfin that adds PostgreSQL database support for .NET 11 preview.
+
+## Features
+
+- ✅ PostgreSQL database provider implementation
+- ✅ Automatic database initialization from SQL scripts
+- ✅ Remote database support with connection string configuration
+- ✅ Database backup/restore via pg_dump/pg_restore
+- ✅ Migration system disabled in favor of SQL scripts
+- ✅ Support for both local and remote PostgreSQL servers
+
+---
+
+## Requirements
+
+### FFmpeg Requirements
+
+**jellyfin-ffmpeg is highly preferred and recommended** for use with Jellyfin Media Server. While standard FFmpeg can be used, the custom `jellyfin-ffmpeg` fork includes specifically targeted fixes, optimizations, and enhanced hardware acceleration support for media streaming that may not be available or prioritized in the upstream version.
+
+#### Why jellyfin-ffmpeg is Preferred:
+
+- **Improved Hardware Acceleration**: Better support for hardware acceleration (NVENC, QuickSync, VA-API) across a wider range of GPUs, reducing the risk of partial acceleration
+- **Reduced Playback Issues**: Specifically built to handle HDR/Dolby Vision content, HLS/fMP4/MPEG-TS streaming, and complex transcoding scenarios better than standard FFmpeg
+- **Optimized Performance**: Often includes more efficient software decoders (like dav1d for AV1)
+- **Pre-configured**: Automatically included with official Docker images, deb packages, and Windows installers
+
+**Link**: [jellyfin-ffmpeg repository](https://github.com/jellyfin/jellyfin-ffmpeg)
+
+#### Installation:
+
+**Debian/Ubuntu** (using Jellyfin repository):
+```bash
+# Add Jellyfin repository (if not already added)
+sudo apt-get install -y software-properties-common
+sudo add-apt-repository universe
+
+# Install jellyfin-ffmpeg
+sudo apt-get update
+sudo apt-get install -y jellyfin-ffmpeg6
+```
+
+**Manual Download**:
+Download from [jellyfin-ffmpeg releases](https://github.com/jellyfin/jellyfin-ffmpeg/releases) and configure the path in Jellyfin settings.
+
+#### Using Standard FFmpeg (Not Recommended):
+
+If using a custom or unofficial installation where jellyfin-ffmpeg is not available, standard FFmpeg might work but could lead to issues with specific transcoding tasks:
+
+```bash
+# Debian/Ubuntu
+sudo apt-get install -y ffmpeg
+
+# RHEL/Fedora
+sudo dnf install -y ffmpeg
+
+# Arch Linux
+sudo pacman -S ffmpeg
+```
+
+**Note**: You may need to manually set the FFmpeg path in Jellyfin's dashboard under **Dashboard → Playback → FFmpeg path**.
+
+### System Dependencies (Linux)
+
+Jellyfin requires certain system libraries to be installed:
+
+#### Debian/Ubuntu-based systems:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y \
+    libfontconfig1 \
+    libfreetype6 \
+    libssl3 \
+    libicu-dev
+```
+
+**Note**: See the [FFmpeg Requirements](#ffmpeg-requirements) section above for installing `jellyfin-ffmpeg`.
+
+#### RHEL/CentOS/Fedora-based systems:
+
+```bash
+sudo dnf install -y \
+    fontconfig \
+    freetype \
+    openssl \
+    libicu
+```
+
+**Note**: See the [FFmpeg Requirements](#ffmpeg-requirements) section above for installing FFmpeg.
+
+#### Arch Linux:
+
+```bash
+sudo pacman -S fontconfig freetype2 openssl icu
+```
+
+**Note**: See the [FFmpeg Requirements](#ffmpeg-requirements) section above for installing FFmpeg.
+
+**Note**: The `libfontconfig1` library is **required** for SkiaSharp (image processing). Without it, Jellyfin will fail to start with:
+```
+libfontconfig.so.1: cannot open shared object file: No such file or directory
+```
+
+### PostgreSQL Requirements
+
+- PostgreSQL 12 or higher (tested with PostgreSQL 18.3)
+- `psql` client tools (for automatic schema initialization)
+- Network access to PostgreSQL server (if using remote database)
+
+#### Install PostgreSQL client tools:
+
+**Debian/Ubuntu**:
+```bash
+sudo apt-get install -y postgresql-client
+```
+
+**RHEL/CentOS/Fedora**:
+```bash
+sudo dnf install -y postgresql
+```
+
+**Verify psql is available**:
+```bash
+psql --version
+```
+
+---
+
+## Database Configuration
+
+### Option 1: Using ConnectionString (Recommended)
+
+Create or edit `config/database.xml` in your Jellyfin data directory:
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<DatabaseConfigurationOptions>
+  <DatabaseType>Jellyfin-PostgreSQL</DatabaseType>
+  <LockingBehavior>NoLock</LockingBehavior>
+  
+  <CustomProviderOptions>
+    <PluginName>Jellyfin-PostgreSQL</PluginName>
+    <PluginAssembly>Jellyfin.Database.Providers.Postgres</PluginAssembly>
+    
+    <!-- Connection string with all parameters -->
+    <ConnectionString>Host=192.168.1.100;Port=5432;Database=jellyfin;Username=jellyfin;Password=your_password_here</ConnectionString>
+  </CustomProviderOptions>
+  
+  <!-- Optional: Backup configuration (works for both local and remote databases) -->
+  <BackupOptions>
+    <PgDumpPath>pg_dump</PgDumpPath>
+    <PgRestorePath>pg_restore</PgRestorePath>
+    <BackupFormat>custom</BackupFormat>
+    <IncludeBlobs>true</IncludeBlobs>
+    <CompressionLevel>6</CompressionLevel>
+    <TimeoutSeconds>1800</TimeoutSeconds>
+    <VerboseOutput>true</VerboseOutput>
+  </BackupOptions>
+</DatabaseConfigurationOptions>
+```
+
+### Option 2: Using Individual Options
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<DatabaseConfigurationOptions>
+  <DatabaseType>Jellyfin-PostgreSQL</DatabaseType>
+  
+  <CustomProviderOptions>
+    <PluginName>Jellyfin-PostgreSQL</PluginName>
+    <PluginAssembly>Jellyfin.Database.Providers.Postgres</PluginAssembly>
+    
+    <Options>
+      <CustomDatabaseOption>
+        <Key>Host</Key>
+        <Value>192.168.1.100</Value>
+      </CustomDatabaseOption>
+      
+      <CustomDatabaseOption>
+        <Key>Port</Key>
+        <Value>5432</Value>
+      </CustomDatabaseOption>
+      
+      <CustomDatabaseOption>
+        <Key>Database</Key>
+        <Value>jellyfin</Value>
+      </CustomDatabaseOption>
+      
+      <CustomDatabaseOption>
+        <Key>Username</Key>
+        <Value>jellyfin</Value>
+      </CustomDatabaseOption>
+      
+      <CustomDatabaseOption>
+        <Key>Password</Key>
+        <Value>your_password_here</Value>
+      </CustomDatabaseOption>
+    </Options>
+  </CustomProviderOptions>
+</DatabaseConfigurationOptions>
+```
+
+### Option 3: Hybrid (ConnectionString + Overrides)
+
+Individual options take precedence over ConnectionString:
+
+```xml
+<CustomProviderOptions>
+  <!-- Base connection -->
+  <ConnectionString>Host=192.168.1.100;Port=5432;Database=jellyfin;Username=jellyfin</ConnectionString>
+  
+  <!-- Override just the password -->
+  <Options>
+    <CustomDatabaseOption>
+      <Key>Password</Key>
+      <Value>production_password</Value>
+    </CustomDatabaseOption>
+  </Options>
+</CustomProviderOptions>
+```
+
+---
+
+## Database Initialization
+
+### Automatic Initialization
+
+When Jellyfin starts with an empty database:
+
+1. **Database Check**: Checks if the database exists (creates if missing)
+2. **Table Check**: Checks if `users.Users` table exists
+3. **Auto-Initialize**: If tables don't exist, automatically runs `sql/schema_init/create_database_schema.sql` via `psql`
+4. **Schema Verification**: Verifies all required schemas and tables are present
+
+**Requirements for automatic initialization**:
+- ✅ `psql` command must be in system PATH
+- ✅ Database must exist (created automatically or manually)
+- ✅ SQL script must be deployed: `sql/schema_init/create_database_schema.sql`
+
+### Manual Initialization
+
+If `psql` is not available or automatic initialization fails:
+
+```bash
+# Create database first
+createdb -U postgres jellyfin
+
+# Run schema creation script
+psql -U postgres -d jellyfin -f /path/to/jellyfin/sql/schema_init/create_database_schema.sql
+```
+
+---
+
+## Startup Logs
+
+### Successful Startup (Empty Database):
+
+```

+## Troubleshooting
+
+### Error: `libfontconfig.so.1: cannot open shared object file`
+
+**Cause**: Missing system dependency
+
+**Solution**:
+```bash
+# Debian/Ubuntu
+sudo apt-get install -y libfontconfig1
+
+# RHEL/Fedora
+sudo dnf install -y fontconfig
+```
+
+### Error: `psql command not found`
+
+**Cause**: PostgreSQL client tools not installed
+
+**Solution**:
+```bash
+# Debian/Ubuntu
+sudo apt-get install -y postgresql-client
+
+# RHEL/Fedora
+sudo dnf install -y postgresql
+```
+
+### Error: `Failed to connect to 127.0.0.1:5432`
+
+**Cause**: Configuration not loading correctly (using default localhost)
+
+**Solution**:
+- Verify `database.xml` is in the correct location (`/var/lib/jellyfin/config/database.xml` on Linux)
+- Check that ConnectionString or individual Options are properly configured
+- Ensure Host is set to your remote server IP/hostname
+
+### Error: `database "jellyfin" does not exist`
+
+**Cause**: Database wasn't created automatically (rare)
+
+**Solution**:
+```bash
+# Create database manually
+createdb -U postgres -h your-server jellyfin
+
+# Grant privileges
+psql -U postgres -h your-server -c "GRANT ALL PRIVILEGES ON DATABASE jellyfin TO jellyfin;"
+
+# Restart Jellyfin (it will create tables automatically)
+```
+
+---
+
+## Architecture
+
+### Database Schema
+
+- `activitylog` - Activity log entries
+- `authentication` - API keys, devices, device options
+- `displaypreferences` - User display preferences
+- `library` - Media library data (BaseItems, metadata, etc.)
+- `users` - User accounts, permissions, preferences
+
+### Migration System
+
+**Entity Framework migrations are DISABLED** for .NET 11 preview. Schema changes are managed via SQL scripts:
+
+- **Core migrations**: Disabled (no database structure changes via EF)
+- **Application migrations**: Enabled (configuration and data migrations only)
+
+**Why**: EF migrations in preview builds can cause schema inconsistencies. SQL scripts provide reliable schema management.
+

+
+## Backup and Restore
+
+### Automatic Backups (via pg_dump)
+
+Configured in `database.xml`:
+
+```xml
+<BackupOptions>
+  <PgDumpPath>pg_dump</PgDumpPath>
+  <BackupFormat>custom</BackupFormat>
+  <CompressionLevel>6</CompressionLevel>
+</BackupOptions>
+```
+
+**Works for both local and remote databases!**
+
+### Manual Backup
+
+```bash
+# Backup to custom format (compressed)
+pg_dump -h your-server -U jellyfin -d jellyfin -Fc -f jellyfin_backup.dump
+
+# Backup to SQL format
+pg_dump -h your-server -U jellyfin -d jellyfin -f jellyfin_backup.sql
+```
+
+### Manual Restore
+
+```bash
+# Restore from custom format
+pg_restore -h your-server -U jellyfin -d jellyfin jellyfin_backup.dump
+
+# Restore from SQL format
+psql -h your-server -U jellyfin -d jellyfin -f jellyfin_backup.sql
+```
+
+---
+
+## Troubleshooting Connection Issues
+
+### Error: `57P01: terminating connection due to administrator command`
+
+**Cause**: PostgreSQL server forcibly terminated the connection during an operation
+
+**Common reasons**:
+- PostgreSQL server restart or reload
+- Connection timeout (statement_timeout, idle_in_transaction_session_timeout)
+- Manual connection termination via `pg_terminate_backend()`
+- Network instability or firewall issues
+- Resource limits exceeded (max_connections, memory pressure)
+
+**Solutions**:
+
+#### 1. Configure Automatic Retry (Already Enabled)
+
+Jellyfin now includes automatic retry logic for transient failures:
+- **Max retries**: 3 attempts
+- **Max delay**: 5 seconds between retries
+- **Retryable errors**: Includes `57P01` (connection termination)
+
+#### 2. Increase PostgreSQL Timeouts
+
+Edit PostgreSQL configuration (`/etc/postgresql/*/main/postgresql.conf`):
+
+```
+# Increase statement timeout
+statement_timeout = 300000              # 5 minutes (in milliseconds)
+
+# Increase idle transaction timeout
+idle_in_transaction_session_timeout = 600000  # 10 minutes
+
+# Enable TCP keepalives (prevent network timeouts)
+tcp_keepalives_idle = 60                # seconds
+tcp_keepalives_interval = 10            # seconds
+tcp_keepalives_count = 6
+```
+
+Reload PostgreSQL:
+```bash
+sudo systemctl reload postgresql
+# OR
+psql -U postgres -c "SELECT pg_reload_conf();"
+```
+
+#### 3. Optimize Connection String
+
+Add keepalive and timeout parameters to your connection string:
+
+```xml
+<ConnectionString>Host=192.168.129.253;Port=5432;Database=jellyfin;Username=jellyfin;Password=yourpass;Pooling=True;Minimum Pool Size=0;Maximum Pool Size=50;Connection Idle Lifetime=300;Connection Pruning Interval=10;Timeout=30;Command Timeout=300;Keepalive=60</ConnectionString>
+```
+
+**Key parameters**:
+- `Timeout=30` - Connection establishment timeout (30 seconds)
+- `Command Timeout=300` - Query execution timeout (5 minutes)
+- `Keepalive=60` - TCP keepalive interval (60 seconds)
+- `Connection Idle Lifetime=300` - Close idle connections after 5 minutes
+- `Connection Pruning Interval=10` - Check for stale connections every 10 seconds
+
+#### 4. Check PostgreSQL Logs
+
+On your PostgreSQL server:
+
+```bash
+# View recent logs
+sudo tail -f /var/log/postgresql/postgresql-*.log
+
+# Or check systemd journal
+sudo journalctl -u postgresql -n 100 --no-pager
+```
+
+Look for:
+- `received fast shutdown request`
+- `terminating connection`
+- `too many connections`
+- `out of memory`
+
+#### 5. Monitor Active Connections
+
+```sql
+-- Check current connections
+SELECT 
+    datname, 
+    usename, 
+    application_name,
+    state,
+    state_change
+FROM pg_stat_activity
+WHERE datname = 'jellyfin'
+ORDER BY state_change DESC;
+
+-- Check connection limits
+SELECT 
+    (SELECT setting::int FROM pg_settings WHERE name = 'max_connections') AS max_connections,
+    (SELECT COUNT(*) FROM pg_stat_activity) AS current_connections,
+    (SELECT COUNT(*) FROM pg_stat_activity WHERE datname = 'jellyfin') AS jellyfin_connections;
+```

+## Column Naming Rules
+
+### SnakeCaseNamingConvention Conversion Rules
+
+```csharp
+// From SnakeCaseNamingConvention.cs - regex patterns applied:
+// Rule 1: ([A-Z]+)([A-Z][a-z])  → "$1_$2"   // Consecutive capitals: HTTPServer → HTTP_Server
+// Rule 2: ([a-z\d])([A-Z])      → "$1_$2"   // Lowercase/digit to capital: dateCreated → date_Created
+// Rule 3: .ToLowerInvariant()                // Lowercase: date_Created → date_created
+```
+
+### Common Column Conversions
+
+Single-Word Columns:
+- `"Id"` → `id`
+- `"Name"` → `name`
+- `"Type"` → `type`
+- `"UserId"` → `user_id`
+- `"ItemId"` → `item_id`
+
+Multi-Word Columns:
+- `"DateCreated"` → `date_created`
+- `"DateModified"` → `date_modified`
+- `"DateLastActivity"` → `date_last_activity`
+- `"AccessToken"` → `access_token`
+- `"IsMovie"` → `is_movie`

+
+## Conversion Strategy in create_database_schema.sql
+
+### Phase 1: Table Definition Lines
+Find and replace quoted PascalCase table names immediately after `CREATE TABLE`:
+- `CREATE TABLE activitylog."ActivityLogs"` → `CREATE TABLE activitylog.activity_logs`
+- `CREATE TABLE authentication."ApiKeys"` → `CREATE TABLE authentication.api_keys`
+- etc. (all 19 tables in schema sections)
+
+### Phase 2: Column Definitions
+Within each `CREATE TABLE` block, replace all quoted column names:
+- `"Id"` → `id`
+- `"Name"` → `name`
+- `"DateCreated"` → `date_created`
+- etc. (200+ column replacements across all tables)
+
+### Phase 3: Sequence Names
+Update sequence definitions to match renamed tables:
+- `SEQUENCE NAME activitylog."ActivityLogs_Id_seq"` → `SEQUENCE NAME activitylog.activity_logs_id_seq`
+- etc.
+
+### Phase 4: Constraint References
+Update all foreign key and constraint definitions:
+- `CONSTRAINT "fk_base_items_users_user_id" FOREIGN KEY ("BaseItemId") REFERENCES users."Users" ("Id")` 
+  → `CONSTRAINT fk_base_items_users_user_id FOREIGN KEY (base_item_id) REFERENCES users.users (id)`
+
+### Phase 5: Index References
+Update index definitions:
+- `CREATE INDEX "idx_activity_logs_user_id" ON activitylog."ActivityLogs" ("UserId")`
+  → `CREATE INDEX idx_activity_logs_user_id ON activitylog.activity_logs (user_id)`
+
+### Phase 6: Special Table (__EFMigrationsHistory)
+Update system table for consistency:
+- `"__EFMigrationsHistory"` → `__ef_migrations_history`
+- All its columns follow the same snake_case rule
+
+---
+
+## File Location
+- **Source**: `Jellyfin.Server/sql/schema_init/create_database_schema.sql` (1879 lines)
+- **Output**: Same file (in-place conversion)

+# WebSocket Authentication Guide
+
+## Overview
+
+WebSocket connections to Jellyfin servers require authentication. This guide explains how to properly authenticate WebSocket connections using API tokens.
+
+## Authentication Methods
+
+### 1. Query String Parameter (Recommended for WebSocket)
+
+The simplest and most compatible method for WebSocket connections.
+
+**URL Format:**
+```
+ws://jellyfin-server:8096/socket?api_key=YOUR_API_TOKEN
+wss://jellyfin-server:8096/socket?api_key=YOUR_API_TOKEN  (for HTTPS)
+```
+
+**JavaScript Example:**
+```javascript
+const token = "YOUR_API_KEY";
+const ws = new WebSocket(`ws://jellyfin-server:8096/socket?api_key=${token}`);
+
+ws.onopen = function(event) {
+	console.log("WebSocket connection established with authentication");
+};
+
+ws.onerror = function(event) {
+	console.error("WebSocket error:", event);
+};
+
+ws.onmessage = function(event) {
+	const message = JSON.parse(event.data);
+	console.log("Received message:", message);
+};
+
+ws.onclose = function(event) {
+	console.log("WebSocket connection closed");
+};
+```
+
+**Python Example:**
+```python
+import asyncio
+import websockets
+import json
+
+async def connect_with_token():
+	token = "YOUR_API_KEY"
+	uri = f"ws://jellyfin-server:8096/socket?api_key={token}"
+
+	async with websockets.connect(uri) as websocket:
+		print("Connected to Jellyfin WebSocket")
+
+		# Receive messages
+		async for message in websocket:
+			data = json.loads(message)
+			print(f"Received: {data}")
+
+asyncio.run(connect_with_token())
+```
+
+**C# Example:**
+```csharp
+using System;
+using System.Net.WebSockets;
+using System.Threading;
+using System.Threading.Tasks;
+
+public class JellyfinWebSocketClient
+{
+	public async Task ConnectAsync(string serverUrl, string token)
+	{
+		var uri = new Uri($"ws://{serverUrl}:8096/socket?api_key={token}");
+
+		using (var client = new ClientWebSocket())
+		{
+			await client.ConnectAsync(uri, CancellationToken.None);
+
+			Console.WriteLine("Connected to Jellyfin WebSocket");
+
+			// Receive messages
+			var buffer = new byte[1024 * 4];
+			while (client.State == WebSocketState.Open)
+			{
+				var result = await client.ReceiveAsync(
+					new ArraySegment<byte>(buffer),
+					CancellationToken.None);
+
+				if (result.MessageType == WebSocketMessageType.Text)
+				{
+					var message = System.Text.Encoding.UTF8.GetString(
+						buffer, 0, result.Count);
+					Console.WriteLine($"Received: {message}");
+				}
+			}
+		}
+	}
+}
+```
+
+### 2. Authorization Header (Alternative)
+
+For advanced use cases, you can also use the Authorization header.
+
+**Header Format:**
+```
+Authorization: MediaBrowser Device="ClientName", DeviceId="unique-id", Version="1.0", Token="YOUR_API_TOKEN"
+```
+
+**Note:** Some WebSocket implementations may not support custom headers during the upgrade handshake. Query parameters are recommended.
+
+## Obtaining an API Token
+
+### Via Server UI
+1. Navigate to your Jellyfin server dashboard
+2. Go to Settings → API Keys (or similar, depending on version)
+3. Create a new API key
+4. Copy the token to use in your WebSocket connection
+
+### Programmatically
+Use the REST API to create API keys:
+```bash
+curl -X POST "http://jellyfin-server:8096/Auth/Keys" \
+  -H "Authorization: MediaBrowser Token=existing_token" \
+  -H "Content-Type: application/json" \
+  -d '{"AppName": "My WebSocket Client"}'
+```
+
+## Common Issues
+
+### Connection Refused / 401 Unauthorized
+- Verify the API token is correct
+- Ensure the token hasn't expired
+- Check that the WebSocket endpoint path is correct (`/socket`)
+
+### Token Not Found
+- Verify the query parameter is URL-encoded properly
+- Ensure the parameter name is correct: `api_key` (lowercase)
+- Check server logs for authentication errors
+
+### WebSocket Connection Fails Immediately
+- Confirm the server is reachable
+- Check firewall rules allow WebSocket connections
+- Try with `wss://` (secure WebSocket) if using HTTPS
+
+## Server Configuration
+
+The server automatically extracts tokens from:
+1. Authorization header (MediaBrowser Token parameter)
+2. Query string `api_key` parameter
+3. Query string `ApiKey` parameter
+4. Legacy headers (if enabled in config)
+
+No special server configuration is required for WebSocket authentication to work.
+
+## Security Considerations
+
+- Always use `wss://` (secure WebSocket) when connecting over untrusted networks
+- Keep API tokens secure and rotate them periodically
+- Use separate tokens for different clients/applications
+- Consider implementing token expiration in your server configuration
