Recommended action: Always release in finally (or use pool.query for single statements); monitor pool.totalCount/idleCount/waitingCount; size max vs server connection limits; for the connect-timeout variant check host/port/TLS reachability. Option: Release clients in finally [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. const client = await pool.connect(); try { ... } finally { client.release() } 2. Use pool.query() when no transaction is needed Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
