You can perform all sorts of arithmetic operations inside a query in
Postgres, although sometimes you ave to be a bit clever with the syntax.
(I'm not sure how much of it is strict SQL92 though.) It would be a
nightmare working with datetimes if you couldn't subtract them from each
other, add intervals, etc.
