Inside the charms

Charmed PgBouncer ships the latest PgBouncer 1.21.0-0ubuntu0.22.04.1~ppa1
The Prometheus pgbouncer-exporter is “0.7.0-0ubuntu0.22.04.1~ppa1”
VM charms based on the Charmed PgBouncer snap revisions 3 (amd64) and 4 (arm64).

Note: This release of the PgBouncer charm uses the new charmed-pgbouncer snap. In previous releases, it was based on the charmed-postgresql snap.

Upgrading will automatically switch the snaps.

Subordinate charms support LTS 22.04(jammy) and 20.04(focal) only

Technical notes

Check PgBouncer’s system requirements
Note: juju 3.1.6 doesn’t report when pre-upgrade-check action fails. Therefore, it is recommended to redeploy pgbouncer charm on Juju 3.1.7+
Use this operator together with the Charmed PostgreSQL operator
