Yeah, same here. Obviously, it'd be better to spend effort on getting the bug fix committed than to spend effort on some cosmetic workaround. The fact that the failure is in the isolation tests not the core regression tests reduces my level of concern somewhat about shipping it this way. I think that packagers typically run the core tests not check-world during package verification, so they won't hit this. regards, tom lane
