tables not in list

Hi List,

I have a list of table names and I am trying to confirm that they are all in
my postgres db. But what I want returned is a list/array of ones that are
in my list but not in the db. So for example:

CREATE TABLE test
(
somecol integer
) WITHOUT OIDS;

CREATE TABLE bar
(
barcol integer
) WITHOUT OIDS;

Now if I were to have a list of table names that included 'test', 'bar', and
'foo', then how do I get 'foo' to return. Here is what I have, but it
returns the ones that are in the list and I want the opposite of that.

select array(
select table_name::text from information_schema.tables where
table_catalog='postgres' and table_type='BASE TABLE' and
table_schema='public'
and table_name = any (array['test', 'bar', 'foo']))

Thanks in advance for any help on this.
