There's more…

The default behavior for repmgr utility is manual failover.

The repmgr utility also supports automatic failover capabilities. It can automatically detect failures of other nodes and then decide which server should become the new master by voting among all of the still available standby nodes. The repmgr utility supports a witness server to ensure that there are an odd number of voters in order to get a clear winner in any decision.
