I don't see what the point of that effort is. All it's doing is to make it
ever harder to write tests. IMO we should go diametrically the opposite way
and assume that we have fully built postgres when running tests.

No, it makes absolutely no sense to test e.g. hash killtuples support in
btree_gist.
