You want to use 'SERIAL' or 'BIGSERIAL' data type. Then, for your
insert statement, use the 'RETURNING' clause like this:

CREATE TABLE mytable (
mypkey SERIAL NOT NULL,
somecol VARCHAR(200)
);

INSERT INTO mytable (somecol)
VALUES ('this is a test)
RETURNING mypkey;

You'll get your insert statement to return the integer value generated
by the SERIAL sequence.

These features are way more powerful than AUTO_INCREMENT.
