Promotes a standby to a primary if the current primary has failed. 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.
If the standby promotion succeeds, the server will not need to be restarted. However any other standbys will need to follow the new server, by using repmgr standby follow; if repmgrd is active, it will handle this automatically.
