Oh, I should have looked at the code before commenting ;-).

Yeah, the correct TID value would be ItemPointerGetBlockNumber(tid)
plus the current offnum.  However we don't have enough information
in this function to set t_tableOid correctly, so maybe it would be
best to just set both fields invalid.  Or do nothing --- AFAICS none
of the uses of the heapTuple look at those fields.  Is it worth a few
extra cycles to initialize unused fields of a short-lived heapTuple?
