Ensure 'log_timezone' is set correctly

低レベル 1自動postgres

説明

The log_timezone setting specifies the time zone to use in timestamps within log messages. This value is cluster-wide, so that all sessions will report timestamps consistently. Unless directed otherwise by your organization's logging policy, set this to either GMT or UTC. Expects GMT/UTC; if your policy mandates another zone, accept this finding as an exception. Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.
