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 )
