Indeed.  I was just rebasing my 8-byte-Datum patch onto HEAD, and
noted this and one or two other places still missing DatumGetPointer.
I plan to go ahead and commit a cleanup patch with those fixes and
s/(Datum) NULL/(Datum) 0/g as soon as I've finished testing.

FWIW, I don't love the "DummyDatum" name either.  Maybe InvalidDatum?
