Re: removing "serial" from table definitions.

From what I know, serial is just used to setup a table but it is then
converted to int in the table. Therefore, you probably cannot remove it
since it is not there any more anyway.

To setup table with int instead of serial, you could use this:

CREATE SEQUENCE table_name_id_seq;

CREATE TABLE table_name (
id integer NOT NULL DEFAULT nextval('table_name_id_seq')
);

ALTER SEQUENCE table_name_id_seq
OWNED BY table_name.id;

instead of

CREATE TABLE table_name(
id SERIAL
);
