I have a table that I want to keep track of the user who last modified 
it and the timestamp of the modification. Should I use a trigger or a rule?

CREATE TABLE stampedtable (
	stampedtableid SERIAL PRIMARY KEY,
	updatestamp timestamp NOT NULL DEFAULT now(),
	updateuser name NOT NULL DEFAULT current_user,
	sometext text
);

I suspect that I want a rule, but all the examples in the documentation 
seem to update a separate table and not override (or add) the 
insert/update to the timestamp and name columns.

Thanks,
-Neal
