-----------
HeapTupleHeaderAdjustCmax made the incorrect assumption that the raw
command id is the cmin, when it can in fact be a combo cid. That made rows
incorrectly invisible to a transaction where a tuple was deleted by multiple
aborted subtransactions.

Report and patch Karl Schnaitter. Back-patch to 8.3, where combo cids was
introduced.
