I'm not sure there's an easy way to test it via pg_regress, but if
somebody can come up with something, sure. But why stick to a rule
that is inconvenient for no real benefit? Compiling everything in
src/test/modules when someone runs 'make check-world' would take a
handful of seconds and prevent developer errors like the one that
started this thread. That seems like a slam-dunk from here,
regardless of anything else.
