repmgr standby follow repmgr standby follow repmgr standby follow attach a standby to a new primary 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, use . repmgr standby follow will wait up to standby_follow_timeout seconds (default: 30) to verify the standby has actually connected to the new primary. $ repmgr -f /etc/repmgr.conf standby follow INFO: setting node 3's primary to node 2 NOTICE: restarting server using "pg_ctl -l /var/log/postgres/startup.log -w -D '/var/lib/postgres/data' restart" waiting for server to shut down........ done server stopped waiting for server to start.... done server started NOTICE: STANDBY FOLLOW successful DETAIL: node 3 is now attached to node 2 --dry-run Check prerequisites but don't actually follow a new standby. This does not guarantee the standby can follow the primary; in particular, whether the primary and standby timelines have diverged, can currently only be determined by actually attempting to attach the standby to the primary. -w --wait Wait for a primary to appear. &repmgr; will wait for up to primary_follow_timeout seconds (default: 60 seconds) to verify that the standby is following the new primary. This value can be defined in repmgr.conf. A standby_follow event notification will be generated. If provided, &repmgr; will substitute the placeholders %p with the node ID of the primary being followed, %c with its conninfo string, and %a with its node name.
