Funny that there'd be another bug associated with
heap_prepare_freeze_tuple() so soon after the last one was discovered.
Are you aware of the other one [1]?
BTW, I just posted a patch to enhance amcheck, to allow it to verify
that an index has all the entries that it ought to [2]. Perhaps you'd
find it useful for this kind of thing. I welcome your feedback on
that.
