An application opens thousands of short-lived connections and the server hits its connection limit. Which built-in feature addresses this?
- A Increase max_connections indefinitely
- B Enable the built-in PgBouncer connection pooler (correct answer)
- C Add a read replica
- D Enable query store
Shortcut: Flexible Server includes PgBouncer. Transaction-mode pooling multiplexes many client connections onto a small set of server connections, which is the correct fix for connection churn.
