put all your tables in a new table (public.tables)
select table_name from public.tables
where public.tables.table_name not in (select table_name from information_schema.tables where table_catalog='postgres' and table_type='BASE TABLE' and table_schema='public')

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.
