## 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
