Uh ... telling it what the version is doesn't make that true, so I'd have no confidence in a test^H^H^H^Hkluge done that way. The way to test is to point it at an *actual* back-branch server. Andrew has a buildfarm module that does precisely that, although I'm not sure what its test dataset is --- probably the regression database from each branch. I also have a habit of doing such testing manually whenever I touch version-sensitive parts of pg_dump. Dunno about the idea of running the pg_dump TAP tests against back branches. I find that code sufficiently unreadable that maintaining several more copies of it doesn't sound like fun at all. regards, tom lane
