What I'm really trying to do is to write a rule of the form:

CREATE OR REPLACE VIEW table AS SELECT * FROM real_table;

CREATE OR REPLACE RULE myrule AS ON INSERT TO table DO INSTEAD INSERT
INTO real_table VALUES (func(NEW));

Basically to require all inserts to be "cleaned" by func. The reason
for this is we're trying to keep a modification history of the table.
Insert is the simple case- the update and delete rules will be much more
interesting.

This is the current solution I'm going with. The main problem I have
with this is stylistic- it changes the result psql displays from an
insert response to a select response.
