Fix pfree issue in presorted DISTINCT aggregate code The logic in this area was recently changed in 7da51590e, however, in that commit, I neglected to consider that the conditions in which we should pfree the old Datum needed to be updated after that change. This could result in trying to pfree a NULL value, as was demonstrated by Alexander Lakhin.
