Hmm, doesn't vacuum skip pages when they are pinned? I don't think VACUUM FREEZE would be treated especially -- only "aggressive" wraparound would be an exception, IIRC. This would reflect in the relfrozenxid for the table after vacuum, but I'm not sure if there's a decent way to make the regression tests reflect that. > Also, not really a bug, but why is this test script running exactly > the same query twice in a row?
