I'd say there's no difference between the rule you'd use
for COPYing and the rule you'd use for INSERTing,
which is why my patch produces an
INSERT statement and then proceeds to (attempt
to) execute the statement for every row of data
to be copied. If you don't have a rule that allows
INSERT into the view you get (the already existing)
error with a hint that tells you to make an INSERT
rule.
