I'm not sure fixing "only" this single missing clean up makes sense. I think,
that the main purpose of those would be to be able to run "make installcheck EXTRA_REGRESS_OPTS="--use-existing""
multiple times on the same running instance without any errors. If that's the
case, then from what I can see after a quick test, the task would be way larger
that this patch.
