Hm, I at least used to get a lot of spurious failures with this. I
e.g. don't think the free port selection is race free.  Also that
doesn't solve the issue of the time spent in repetitive initdbs - but
that's mainly in contrib, and we probably solve that there by having a
special target in contrib/ building a cluster once.

Ah, interesting.

Yea, I indeed see that. Probably could do a top-level prerequisite for
check on a check-world subset that includes docs?
