What it does
Complements log_connections by recording when sessions end and how long they lasted. Pairing the two lets you reconstruct session lifetimes and catch unexpectedly long-lived or rapidly-cycling connections.
How to tune it
Enable alongside log_connections for auditing. The session-duration figure is handy for spotting connection leaks (sessions that live far longer than expected).
