## Migration Fix for Railway Database
- Railway PostgreSQL already has access_url_name/display_url_name columns
- Previous migration tried to add existing columns → DuplicateColumn error
- New migration checks if columns exist before adding them
## Smart Migration Logic
✅ Check information_schema for existing columns
✅ Add columns only if they don't exist
✅ Skip if columns already present (Railway case)
✅ Works for both fresh and existing databases
## Error Fixed
❌ Was: column 'access_url_name' of relation 'agents_agent' already exists
✅ Now: Migration succeeds regardless of existing schema state
## Result
- Railway deployment will complete successfully
- populate_agents will run and create all 5 agents
- Marketplace will show agents again

## Critical Database Fix
- Add migration for missing access_url_name and display_url_name fields
- Railway PostgreSQL has these fields as NOT NULL from newer schema
- ae303c2 agent creation commands don't provide these fields
- Migration makes fields optional with empty string defaults
## Error Fixed
❌ Was: null value in column 'access_url_name' violates not-null constraint
✅ Now: Fields are optional, agent creation will succeed
## Result
- populate_agents command will now work on Railway
- All 5 agents should appear in production marketplace
- No more database constraint violations
