Subject: Sub Select inside Check ?

Hi,

I'm trying to create this table with a Check that fails.

I'm using 'Check' instead of 'References' due to poor db schema ( before 
me .. )

Here is my error message:
ERROR: cannot use subselect in CHECK constraint expression

CREATE TABLE cp_retailers
(
ret_id serial PRIMARY KEY,
ret_name varchar(120) NOT NULL,
ret_address1 varchar(120),
ret_address2 varchar(120),
sub_id integer NOT NULL CHECK
                            ( EXISTS
                            ( SELECT sub_id FROM suburbs )  
                            )
);

I guess that say's it all - no sub select's in Check or am I on the 
wrong track ?

Thank you kindly
Regards
Rudi.
