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 :-( regards, tom lane
