Attaches the standby to a new primary. This command requires a valid repmgr.conf file for the standby, either specified explicitly with -f/--config-file or located in a default location; no additional arguments are required.
This command will force a restart of the standby server, which must be running. It can only be used to attach an active standby to the current primary node (and not to another standby).
To re-add an inactive node to the replication cluster, see repmgr node rejoin
