Type: enum
Default: warning
Context: superuser
Restart: false
Values: [debug5, debug4, debug3, debug2, debug1, info, notice, warning, error, log, fatal, panic]

Controls which message levels are written to the server log. Valid values are DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, INFO, NOTICE, WARNING, ERROR, LOG, FATAL, and PANIC. Each level includes all the levels that follow it. The later the level, the fewer messages are sent to the log. The default is WARNING. Note that LOG has a different rank here than in client_min_messages. Only superusers and users with the appropriate SET privilege can change this setting.


Unless doing serious troubleshooting. If you want to output parses and plans, set to DEBUG1.
