Actually i have to update multiple columns my original 
query was:

UPDATE  profile_master    SET

 title1=a.title1 , fname1=a.fname1 , mname1=a.mname1 ,
 lname1=a.lname1 , desg1 = a.desg1 FROM 

(
   SELECT company_id , titile as title1 ,fname as fname1 ,mname as mname1 ,
   lname as lname1 ,company_position as desg1  from public.catalog_key_contacts as b 
   where  b.company_id=profile_master.company_id order by contact_id limit 1 offset 0)  

as a WHERE
