Perform a major rollback

Example: PostgreSQL 15 → PostgreSQL 14

Currently, this charm only supports PostgreSQL 14. Therefore, only minor rollbacks are possible.

Canonical is NOT planning to support in-place rollbacks for the major PostgreSQL version change as the old PostgreSQL cluster installation will stay nearby and can be reused for the rollback.
