PostgreSQL database instance ‘log_min_messages’ database flag should be set appropriately


The PostgreSQL database instance flag ‘log_min_messages’ controls which message levels are written to the server log. Valid values include INFO, WARNING, and ERROR. Each level includes all the levels that follow it. The default is WARNING. If this flag is not set to the correct value, important messages useful for troubleshooting may not be logged.
