Discussão: Database connection pooling and its limits
Entradas
An external pooler is one more component to run, monitor and upgrade. For a single application instance, the framework's in-process pool with a sensible cap is usually enough, and the article's suggestion to introduce PgBouncer early adds operational surface before it is needed. Introduce it when the number of application processes times their pool size approaches the database's connection limit.
With PgBouncer in transaction mode, session-level features (prepared statements by name, `SET` without `LOCAL`, advisory locks held across transactions, `LISTEN`) break in ways that look random. Newer PgBouncer versions support protocol-level prepared statements, but the rest still applies; audit the application for session state before switching modes.
