I apologize for the silence.
t_a as been created as
CREATE TABLE t_a as SELECT userid,category_id from eyp_listing where userid=21742 and size ilike '%WEBFL%'
EXCEPT SELECT userid,category_id from company_export_profile where userid=21742 ;
so the subquery is basically
( SELECT userid,category_id from eyp_listing where userid=21742 and
size ilike '%WEBFL%' EXCEPT SELECT userid,category_id from company_export_profile
where userid=21742 )
