Log Message:
repmgr: updated to 5.3.0

repmgr 5.3.0 is a major release.

This release provides support for PostgreSQL 14, released in September 2021.

A.1.1. Improvements

repmgr standby switchover: Improve handling of node rejoin failure on the \ 
demotion candidate.

Previously repmgr did not check whether repmgr node rejoin actually succeeded on \ 
the demotion candidate, and would always wait up to node_rejoin_timeout seconds \ 
for it to attach to the promotion candidate, even if this would never happen.

This makes it easier to identify unexpected events during a switchover \ 
operation, such as the demotion candidate being unexpectedly restarted by an \ 
external process.

Note that the output of the repmgr node rejoin operation on the demotion \ 
candidate will now be logged to a temporary file on that node; the location of \ 
the file will be reported in the error message, if one is emitted.

repmgrd: at startup, if node record is marked as "inactive", attempt \ 
to set it to "active".

This behaviour can be overridden by setting the configuration parameter \ 
repmgrd_exit_on_inactive_node to true.

repmgr node rejoin: emit rejoin target note information as NOTICE.

This makes it clearer what repmgr is trying to do.

repmgr node check: option --repmgrd added to check repmgrd status.

Add %p event notification parameter providing the node ID of the former primary \ 
for the repmgrd_failover_promote event.

A.1.2. Bug fixes

repmgr standby clone: if using --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 now set slot_name in the node record, if it \ 
was previously empty.

repmgrd: rename internal shared library functions to minimize the risk of \ 
clashes with other shared libraries.

This does not affect user-facing SQL functions. However an upgrade of the \ 
installed extension version is required.

repmgrd: ensure short option -s is accepted.
