- Remove postgresql-client installation (causes 150s+ hangs due to network)
- Add db_init.py: Pure Python PostgreSQL checks using psycopg2-binary
- Simplify startup.sh: Call Python script instead of psql commands
- Build should now complete in <30s instead of hanging
This fixes the deployment timeout issue by avoiding APT network problems entirely.
