I've added support for a 'running' setup in the attached rebased series. A
bunch of preparatory changes were necessary - as it turns out we've introduced
a bunch of role name conflicts between tests.

I had to set it up so that the main regress and isolationtester tests don't
run in parallel with other tests, because they don't pass reliably due to
checking pg_locks etc.

I also found a problem independent of meson [1] / installcheck.

# run all tests that support running against existing server
meson test --setup running

# run just the main pg_regress tests against existing server
meson test --setup running main/regress-running

I've also worked some more on cleaning up other patches in the series,
particularly the precompiled headers one (interesting because it reduces
windows compile times noticably).

Peter, would this address your use case?

I think it'd make sense to add a few toplevel targets to run tests in certain
ways, but I've not done that here.

Greetings,
