I run a master and standby setup with Postgresql 11. The systems are identical from a hardware and software setup. If the master goes down I can do a pg_ctl promote on the standby and point my applications to use the standby (new master).

Once the original master is online, when is an appropriate time to fail back over? And are there any other things besides promote after the failover is done?
