I thought about that approach, but it seemed better to make sure
that things didn't get broken at any isolation level by patches
dealing with DROP INDEX CONCURRENTLY.  If you're sure that could
never happen, we could save a few dozen lines of isolation test

It's not like READ COMMITTED will never get tested -- I would bet
that upwards of 99% of the make installcheck-world runs or make
installcheck -C src/test/isolation runs are at that isolation
