Description

Disconnection may be initiated by the user or forced by the system (as in a timeout) or result from a system or network failure. To the greatest extent possible, all disconnections must be logged. For completeness of forensic analysis, it is necessary to know how long a user's (or other principal's) connection to PostgreSQL lasts. This can be achieved by recording disconnections, in addition to logons/connections, in the audit logs.
