What about this?
delete from eyp_listing where exists (select * from
   eyp_listing el
   left join company_export ce using (userid,category_id)
  where el.userid=21742 and size ilike '%WEBFL%' and ce.userid is null
   and el.userid=eyp_listing.userid
   and el.category_id=eyp_listing.category_id);

It should be solution, but not the answer for your question...
How did you use that sub-select, so it didn't work?
