Code review comment for lp:~paelzer/britney/hints-ubuntu-focal-pglogical-back

pglogical was removed by [1] for postgresql-11 dependency.
Later on it was dropped here by

  branch nick: hints-ubuntu

  message: drop unused hints

That was correct at the time, but now needs to come back as the
new pglogical can work with postgresql-12 and therefore is synced in now.

Use the new force-reset-test [2] as it might come back working and we'd
want to see that to re-check why which we won't realize if we continuously
just badtest it.
