I reworked the tests with another injection point as part of this, this way they shouldn't be flaky on CI and they are significantly faster now. > I'm not sure that "since the server started" is enough for a backup taken from > a standby.

There was really an issue there, I think we can solve that by advancing minrecoverypoint. I kept a test case for this separate for now, as I am unsure if we want to include it in some form. > I think that an atomic would make more sense. Also done.
