Nevermind- that doesn't work either! Here's the new sample code:

-- Begin demo SQL

CREATE SEQUENCE main_id_seq;
CREATE TABLE main (       id INTEGER PRIMARY KEY,       contents VARCHAR
);

CREATE TABLE othertable (       main_id INTEGER REFERENCES main(id)
);              

CREATE RULE main_insert AS  ON INSERT TO main DO       INSERT INTO othertable VALUES (new.id);

INSERT INTO main(id, contents) VALUES (nextval('main_id_seq'), 'Fails here');

-- End demo SQL

The same thing happens. The rule tries to put 2 into othertable. Surely
this is a bug?
