This is intended to ensure that all nodes have a constant LSN while making the failover decision. This feature is experimental and needs to be explicitly enabled with the configuration file option "standby_disconnect_on_failover". Note enabling this option will result in a delay in the failover decision until the WAL receiver is disconnected on all nodes.
