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.
