You'll have to begin the transaction before the function is run (implicit
within a query if not in a xact). End the transaction after the function
returns. If the function does a RAISE EXCEPTION ''I don't like that'', then
the transaction is aborted during the function. Again, within a query (which
triggers your function), a transaction is begun implicity if a transaction is
not begun explicity beforehand with BEGIN.
