Postgres Repmgr version mismatch error

[BMartinos]

A recent error has been noted where the current database-postgres fails to start after trigger a new deployment on an existing deployment.

The database-postgres packages makes use of version 14 of the supplied images. A few days ago, a new has was built under the same tag version which introduced a breaking change on existing deployments.

The new version 14 hash requires an updated repmgr version to be installed and used. Because this isnt installed in the current version, the container fails to start up, and thus prevents other services from starting up

Temp Fix:

Pin the specific hash version before the change occurred to ensure the database can start up under the old version
