repmgr 4.2 is a major release, with the main new feature being the ability to pause repmgrd, e.g. during planned maintenance operations. Various other usability enhancements and a couple of bug fixes are also included.
repmgr 4.1.1 contains a number of usability enhancements and bug fixes.
We recommend upgrading to this version as soon as possible. This release can be installed as a simple package upgrade from repmgr 4.0 ~ 4.1.0; repmgrd (if running) should be restarted. See Upgrading repmgr for more details.
4.1.0:
Configuration file changes
* Default for log_level is now INFO. This produces additional informative log output, without creating excessive additional log file volume, and matches the setting assumed for examples in the documentation.
* recovery_min_apply_delay now accepts a minimum value of zero
repmgr enhancements
* repmgr: always exit with an error if an unrecognised command line option is provided. This matches the behaviour of other PostgreSQL utilities such as psql.
* repmgr: add -q/--quiet option to suppress non-error output.
* repmgr cluster show, repmgr node check and repmgr node status return non-zero exit code if node status issues detected.
* Add --csv output option for repmgr cluster event.
* repmgr witness unregister can be run on any node, by providing the ID of the witness node with --node-id.
* repmgr standby switchover will refuse to run if an exclusive backup is taking place on the current primary.
repmgrd enhancements
repmgrd: create a PID file by default. For details, see repmgrd's PID file.
repmgrd: daemonize process by default. In case, for whatever reason, the user does not wish to daemonize the process, provide --daemonize=false.
Bug fixes
repmgr standby register --wait-sync: fix behaviour when no timeout provided.
repmgr cluster cleanup: add missing help options.
Ensure witness node follows new primary after switchover.
repmgr node check and repmgr node status: fix witness node handling.
Based on package provided by Matthieu Guegan in joyent/pkgsrc#49
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.
