          Controls which message levels are written to the server log
          for system modules needed for recovery processing. This allows
!         the user to override the normal setting of log_min_messages,
          but only for specific messages. This is intended for use in
          debugging Hot Standby.
          Valid values are <literal>DEBUG5</>, <literal>DEBUG4</>,
