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.

Lee
