Insert question null/not null serial, etc.

I downloaded the port for Postgres for PHP-NUKE.

All insert statements are as follows:

For table:
Table "nuke_referer"
Column | Type | Modifiers
--------+------------------------+----------------------------------------------------------
rid | integer | not null default
nextval('"nuke_referer_rid_seq"'::text)
url | character varying(100) | not null default ''
Primary key: nuke_referer_pkey

insert into nuke_referer values (NULL,'whatever');

Which gives me the error: "Warning: pg_exec(): Query failed: ERROR:
ExecAppend: Fail to add null value in not null attribute rid"

Since nowhere in the 3000 files of PHP-Nuke do they actually name columns
for insert commands, does anyone have any suggestions? Can NULL be
replaced with anything? (Keep in mind I'd like something I can globally
change, naming tables/columns individually is out of the question.)
