You are right, this was already a known issue (and I had it buried in
my to-do list, in fact).  I rediscovered it while puzzling over some
of the corrupted-data reports we've seen lately.

I'll go ahead and make the change in current sources.  Does anyone
have a strong feeling about whether or not to back-patch it into
REL7_0 branch for the upcoming 7.0.3 release?
        regards, tom lane
