According the the manual. Serial type is really a short hand notation for:

CREATE SEQUENCE tablename_colname_seq;
CREATE TABLE tablename (
colname integer DEFAULT nextval('tablename_colname_seq') NOT NULL
);

So it insure that your id increments correctly you could specify DEFAULT as your entry for that
field in your insert command.
