You are trying to pass a null to user_id which won't work.

In MySQL that is traditionally how you tell the RDBMS to use the
auto_increment to generate the value. Postgres correctly doesn't allow
that (since you might actually try to set a field to NULL accidentally
in which case an error is expected).
The portable (and correct) way to do it is to use the DEFAULT keyword
like this:
INSERT INTO some_table (id_field) VALUES (DEFAULT);
I just tested on MySQL 5.0.32 and that syntax works fine.
