Good idea as far as speeding check-world and buildfarm runs, but I wonder
if we wouldn't be losing test coverage. Seeing the number of times that
buildfarm runs have gotten through "make check" only to fail at the
re-run in pg_upgrade, it seems clear to me that there is something
different about the execution environment in the latter case. I've
never been able to pin down quite what :-(
