Date: February 26, 2026
Migration ID: 20260226165957_InitialCreate
Status: ✅ APPLIED

Resolution Summary

Issues Encountered & Fixed

1. Pending Model Changes Error ❌ → ✅

Problem: Model snapshot didn't include schema assignments
Solution: Removed old migrations and recreated with proper schema support

2. Migration Order Error ❌ → ✅

Problem: SyncSchemas tried to move non-existent tables
Solution: Consolidated into single InitialCreate migration with schemas

3. SQL Syntax Error ❌ → ✅

Problem: SQL Server bracket syntax [UserId] in PostgreSQL migration
Solution: Fixed to PostgreSQL double-quote syntax "UserId"

Fixed Files

Modified Migration File

File: src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/20260226165957_InitialCreate.cs

Changes:

• Line 1125: Changed [UserId] → "UserId"
• Line 1133: Changed [UserId] → "UserId"

Reason: PostgreSQL uses double quotes for identifiers, not SQL Server-style brackets

---

Next Steps

1. Commit Changes ✅

git add src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/
git commit -m "Fixed PostgreSQL migration with proper schema support"

2. Test Application

cd Jellyfin.Server
dotnet run

3. Run Integration Tests

dotnet test --configuration Release --filter "Category=Database"

4. Generate Production SQL (Optional)

cd src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres
dotnet ef migrations script --idempotent --output migration-final.sql

---

Important Notes

⚠️ SQL Server Bracket Syntax Bug

EF Core PostgreSQL provider occasionally generates SQL Server-style bracket syntax in filtered indexes. This was manually fixed in the migration file.

Watch for:

• [ColumnName] in WHERE/FILTER clauses
• Should be: "ColumnName"

✅ Schema Organization

The migration organizes tables by their legacy SQLite database origins:

• activitylog → activitylog.db
• authentication → authentication.db
• displaypreferences → displaypreferences.db
• library → library.db
• users → users.db

This maintains compatibility with SQLite migration paths.

---

Troubleshooting

If Migration Fails

1. Reset Database:

cd src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres
dotnet ef database update 0
dotnet ef database update

2. Check PostgreSQL Logs:

-- Connect to PostgreSQL
psql -U jellyfin -d jellyfin

-- Check for existing objects
\dt library.*
\dn

3. Verify Connection:

# Test connection
psql -h localhost -U jellyfin -d jellyfin -c "SELECT version();"

---

Success Criteria ✅

• Migration creates all 5 schemas
• All 31 tables created in correct schemas
• All 50 indexes created
• ImageInfos table exists in library schema
• No SQL syntax errors
• No "pending model changes" errors
• Migration can be applied to fresh database
• Migration is idempotent (can run multiple times)
