Fixes Supabase Postgres 'remaining connection slots are reserved' by routing app traffic through the Supabase pooler instead of direct connections. Use when connection counts spike under load, when serverless functions each open their own connection, or after scaling up instances. Not for slow queries or a genuinely u…

Fixes Postgres FATAL: sorry, too many clients already via psycopg2. Use when new connections are refused, when connection count hits max_connections, or when an agent spawns connections without pooling. Not for auth failures, for slow queries, or for pool exhaustion inside one app.

Fixes SQLAlchemy QueuePool timeouts when the pool is exhausted. Use when you see QueuePool limit of size 5 overflow 10 reached, when an agent leaks connections, or when concurrent requests hang on checkout. Not for wrong credentials, for network failures, or for deadlocks in the database.
