We'll want to use ItemPointerGetOffsetNumberNoCheck() where the TID comes from sources we can't verify. e.g user input... '(2,0)'::tid. We want to use ItemPointerGetOffsetNumber() for item pointers that come from locations that we want to ensure are correct. e.g TIDs we're storing in an index. David
