2ndQuadrant today announced the release of repmgr 4.1.1.
[https://www.2ndquadrant.com/en/resources/repmgr/]
repmgr is the most popular tool for PostgreSQL replication and
failover management. It enhances and complements the built-in
replication capabilities in PostgreSQL; making it easy to set up and
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.
Packages are available via public RPM and APT repositories from
2ndQuadrant. Installation packages documentation is available here:
https://repmgr.org/docs/4.1.1/installation-packages.html
repmgr 4.1.1 presents the following usability enhancements:
- repmgr standby switchover --dry-run no longer copies external
configuration files to test if they can be copied; this avoids making
any changes to the target system.
- repmgr cluster cleanup now includes cluster_cleanup event.
- repmgr standby switchover improves detection of free walsenders.
- Improved messages emitted during repmgr standby promote.
This release presents important enhancements to repmgrd, such as:
- Always reopens the log file after receiving SIGHUP, previously this
happened only when a configuration file change was detected.
- Reports version number after logger initialisation.
- Improved cascaded standby failover handling.
- Improved reconnection handling after brief network outages - if
monitoring data is being collected, this could lead to orphaned
sessions on the primary.
- Check promote_command and follow_command are defined when reloading
configuration. These were checked on startup but not reloaded by
repmgrd, making it possible to build repmgrd with invalid values.
For a detailed list of all changes, enhancements, and bug fixes,
please read the complete release notes here:

We recommend upgrading to this version as soon as possible. This
release can be installed as a simple package upgrade from repmgr 4.x.
