check_pgbackrest 2.3 has been released

_Mons, Belgium, May 31, 2022_

`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.
