Well, what about using sequences?
create sequence tralalala;
create table huibui
(
  id integer primary key default nextval('tralalala'),
  field1 references table1,
  and-so-on references all-other-tables
);

How, each time You insert some data in huibui using
insert into huibui (field1, and-son-on) values (?, ..);
the 'tralala' counter will be increased by one (nextval).


Saluti!

You *really* should go glance over the manual.. There is the field type
SERIAL and things called sequences, both could be what you're talking
about....The rest I'll leave up to you :-)

Good luck!!!

CREATE TABLE foo (
  id SERIAL,
  ...
)

it comes out as an int4 or integer type.
