Yes, that clearly isn't true, and the subsequent bit about catalog accesses isn't right either -- they may not be serializable, but that isn't the reason why. I don't particularly object to the warning that "the tests in this routine are correct" (although indeed the fact that they've changed over the years does seem to belie it). So I'm also in favor of just removing the comment entirely. Dan -- Dan R. K.
