repmgr 4.3 Now Available

2ndQuadrant today announced the release of repmgr 4.3 [
https://www.2ndquadrant.com/en/resources/repmgr/] This major release
includes several important enhancements, making usage of repmgr more
flexible and powerful.

repmgr is the most popular tool for PostgreSQL replication and failover
management, which enhances and complements the built-in replication
capabilities in PostgreSQL. This makes repmgr easy to set up to manage
standby servers, check replication status, and perform administrative tasks
such as switchover operations.The repmgrd daemon provides automatic
failover capability to maximize database uptime, and can easily be
integrated with other tools such as PgBouncer for high application
availability.

repmgr 4.3 presents the following usability enhancements:

- repmgr standby follow. Option --upstream-node-id can now be used to
specify another standby to follow.
- repmgr standby follow. Verifies that it is possible to follow another
node.
- repmgr node rejoin. Verifies that it is possible to attach the node to
the current primary.
- Add new commands repmgr daemon start and repmgr daemon stop. Provides a
standardized way of starting and stopping repmgrd.
- repmgr daemon status. Displays the node priority and the interval (in
seconds) since the repmgrd instance last verified its upstream node was
available.
- Add --compact option to repmgr cluster show.Makes it easier to copy the
output as a compact table to emails, chats etc.
- repmgr cluster show. Differentiates between unreachable nodes and nodes
which are running, but rejecting connections. This makes it possible to see
whether a node is unreachable at network level, or if it is running but
rejecting connections for some reason.
- Add --dry-run to repmgr standby promote.
- repmgr --version-number outputs the "raw" repmgr version number. Intended
to be used by scripts, etc. when an easy parseable representation of the
repmgr version is required.
- Add repmgr node check --data-directory-config options. Gives confirmation
that repmgr is correctly configured.
- Add check to repmgr standby switchover. This ensures the data directory
on the demotion candidate is configured correctly in repmgr.conf.
Additionally, it ensures that repmgr, when remotely executed on the
demotion candidate, can correctly verify that PostgreSQL was shut down
cleanly on the demotion.
