There seems nothing wrong with the rules, except that you
should use OLD instead of CURRENT in the update rule too
because CURRENT will disappear in v6.5.
But from the 'UPDATE 0' I guess you're using a Postgres
version prior to v6.4 - right? I fixed the rule system for
v6.4, before that it was so badly broken that you should not
even try.
