It is not clear what you are trying to do. Your Subject line does not quite
agree with the text.

1.) Are you trying to use the same serial number in multiple records
(tuples)? That is what I would infer from your Subject line. If so, and if
id is the primary key, then those multiple tuples better in different tables
(relations).

2.) Are you trying to use a different serial number in each tuple you
insert? That is what your example seems to show.

In either case, I assume there is more than one column (attribute) in each
tuple. So in case 2 you might wish to declare and operate thus:

CREATE TABLE xxxid    serial NOT NULL,name    character varying);

INSERT INTO xxx (name)    SELECT     place_name      FROM     air_bui     WHERE ... ;

If you are trying to use the same serial number in multiple records,
then you should get the serial number direct from the SEQUENCE and plug it
in each tuple as you need it.
