That's why I'd like there to be a regression test script that does the necessary drops. Exactly when and how that gets invoked is certainly open for discussion. In the manual case I'd imagine calling it with EXTRA_TESTS while running the setup of the source database, if it's not run by default. Maybe the buildfarm module could just invoke the same script directly at a suitable point? regards, tom lane
