check_pgbackrest 2.2 has been released

_Mons, Belgium, December 6, 2021_

`check_pgbackrest` is designed to monitor [pgBackRest](https://pgbackrest.org)
backups from Nagios, relying on the status information given by the
[info](https://pgbackrest.org/command.html#command-info) command.

It allows to monitor the backups retention and the consistency of the archived
WAL segments.

Changes in check_pgbackrest 2.2
--------------------------------------------------------------------------------

* The retention service will check if any error was detected during the backup (reported since pgBackRest 2.36).
* Add nagios_strict output format to filter out unsupported types of values from performance data. (Reported by netphantm and Adrien Nayrat)
* Support uncompressed files in the archives service. (Suggested by Jean-Philippe Guérard)
* Add `retention-diff` and `retention-incr` options in the retention service. (Contributed by devopstales)
* Add `retention-age-to-oldest` option in the retention service. (Suggested by Hendrik Schöffmann)
