Is there no way to do this without doing an insert into another table?
I usually resolve this as:
-- this function lets you select from an array
CREATE OR REPLACE FUNCTION "array_to_set" (vaarray anyarray) RETURNS
SETOF anyelement AS
$body$
BEGIN
FOR I IN COALESCE(ARRAY_LOWER(VAARRAY, 1), 1) ..
COALESCE(ARRAY_UPPER(VAARRAY, 1), 0) LOOP
RETURN NEXT VAARRAY[I];
END LOOP;
END
$body$
LANGUAGE 'plpgsql';
select table_name
from array_to_set(array['test', 'bar', 'foo']) as table_name
where table_name not in (select table_name from
information_schema.tables where table_catalog='postgres' and
table_type='BASE TABLE' and table_schema='public')
