Well - normally you specify your column names in an insert, if you
don't want to fill all values or if you are unsure about the sequence
of attributes:
------------------------------------------------------------
mack=> CREATE SEQUENCE stuff_seq;
CREATE
mack=> CREATE TABLE stuff (
mack-> id INTEGER DEFAULT NEXTVAL('stuff_seq') NOT NULL,
mack-> name TEXT,
mack-> number INTEGER
mack-> );
CREATE
mack=> insert into stuff (name, number) values ('something', 123);
INSERT 1403035 1
mack=> select * from stuff;
id|name |number
--+---------+------1|something| 123
(1 row)
mack=>
