This article provides a deep dive into PgBouncer's architecture, explaining why PostgreSQL requires connection pooling and detailing the operational differences between its various pooling modes. It highlights common pitfalls, such as state loss in transaction pooling mode, and aims to clarify the gap between perceived transparency and actual behavior in production environments.
Background
PgBouncer is a widely used lightweight connection pooler for PostgreSQL that helps manage database resources by reusing connections rather than creating new ones for every client request.
