If executing "repmgr standby clone --replication-conf-only" on a node which was set up without replication slots, but the repmgr configuration was since changed to "use_replication_slots=1", repmgr will attempt to create the replication slot. This will however fail if "slot_name" is not set in the node's record, so have repmgr set the slot_name in this case. It might be preferable to preemptively create the slot name for each node when configuring the cluster, however this would be a behavioural change which would be better off in a major release (for example, it's conceivable a user runs sanity checks on the node records and expects to find the slot names empty if replication slots are not in use).
repmgr: Replication Manager for PostgreSQL
repmgr is a suite of open-source tools to manage replication and failover
within a cluster of PostgreSQL servers. It enhances PostgreSQL's built-in
replication capabilities with utilities to set up standby servers, monitor
replication, and perform administrative tasks such as failover or switchover
operations.
The most recent repmgr version (5.2.1) supports all PostgreSQL versions from
9.5 to 13. PostgreSQL 9.4 is also supported, with some restrictions.
repmgr is distributed under the GNU GPL 3 and maintained by EnterpriseDB.
