The repmgr3 implementation required the promotion candidate (standby) to directly work with the demotion candidate's data directory, directly execute server control commands etc. Here we delegated a lot more of that work to the repmgr on the demotion candidate, which reduces the amount of back-and-forth over SSH and generally makes things cleaner and smoother. In particular the repmgr on the demotion candidate will carry out a thorough check that the node is shut down and report the last checkpoint LSN to the promotion candidate; this can then be used to determine whether pg_rewind needs to be executed on the demoted primary before reintegrating it back into the cluster (todo). Also implement "--dry-run" for this action, which will sanity-check the nodes as far as possible without executing the switchover. Additionally some of the new repmgr node commands (or command options) introduced for this can be also executed by the user to obtain additional information about the status of each node.
