pg_autoctl disable maintenance - Disable Postgres maintenance mode on this node

A pg_auto_failover can be put to a maintenance state. The Postgres node is then still registered to the monitor, and is known to be unreliable until maintenance is disabled. A node in the maintenance state is not a candidate for promotion.

Typical use of the maintenance state include Operating System or Postgres reboot, e.g. when applying security upgrades.



 usage: pg_autoctl disable maintenance  [ --pgdata --allow-failover ]
--pgdata      path to data directory
