when i create this table user_mobile_contact_hashes , the function works well. i try to delete those 2 dropped column
infofrom system catalog table , but it can't work  and got other problems. 

putong-contacts=# select insert_user_mobile_contact_hashes(4009, '', ARRAY['7bd94067bb0597bf995c4eb46364a4ce'],
ARRAY['c55288a186d0e6f0e3fb3b66deb65366'],ARRAY[''], false); 
ERROR:  catalog is missing 2 attribute(s) for relid 6097850
