Then you don't remember far enough --- either the HeapTupleHeader change
or the varvarlena change would be enough to prevent that. For that
matter, the pd_flags header field that the patch is already relying on
is new for 8.3.
Adding an xmin field might or might not be a good solution, but to
complain about it on compatibility grounds is silly.
