Connect your PostgreSQL DB (Supabase, Neon, RDS, etc.)
Note: The backend server is hosted on Render (free tier). If it has been idle, the first connection may take ~20–40 seconds to wake up.
Database URL format:
postgresql://USERNAME:PASSWORD@HOST:PORT/DATABASE
Example (Supabase pooler):
postgresql://postgres.projectid:password@aws-1-region.pooler.supabase.com:5432/postgres
