I took the time to specifically check if that would fix the problem.
Unfortunately, it did not. We see exactly the same problem, or at
least amcheck/REINDEX produces exactly the same error. I checked both
Dan's original update_freeze.patch, and your revision that retained
some of the "tupkeep" stuff,
0002-Don-t-freeze-recently-dead-HOT-tuples, which you posted on
September 6th.
