I had a vague idea what the problem might be, but your table definition
proved I was wrong! :-)

This won't sole your problem, but I was wondering why you don't use a
simpler definition like:

CREATE TABLE orderseq
(
orderseq_id SERIAL PRIMARY KEY,
orderseq_name text,
orderseq_number integer,
orderseq_table text,
orderseq_numcol text
);

SERIAL automatically attaches the table's own sequence and does a
DEFAULT nextval

PRIMARY KEY implies NOT NULL & UNIQUE

OIDS=FALSE is the default

My personal preference is just to use the name 'id' for the tables own
primary key, and only prepend the table name when it is foreign key -
makes them stand out more.

Cheers,
Gavin
