got some errors after upgrade poestgresql from 9.5 to 9.6

Hi

I am got a problem after upgrade poestgresql from 9.5 to 9.6 .it's occurred when calling an exits function .

putong-contacts=# select insert_user_mobile_contact_hashes(4009, '', ARRAY['7bd94067bb0597bf995c4eb46364a4ce'], ARRAY['c55288a186d0e6f0e3fb3b66deb65366'], ARRAY[''], false);
ERROR: table row type and query-specified row type do not match
DETAIL: Query provides a value for a dropped column at ordinal position 6.
CONTEXT: SQL statement "UPDATE c
SET
phone_number = phone_number_arr_[i],
name = name_
WHERE
user_id = user_id_
AND
md5_hash11 = md5_hash11_arr_[i]
AND
coalesce(phone_number,'') = ''
AND
char_length(phone_number_arr_[i]) > 0"
PL/pgSQL function insert_user_mobile_contact_hashes(integer,character varying,character varying[],character varying[],character varying[],boolean) line 36 at SQL statement

and here is the column in this table be dropped

putong-contacts=# select * from pg_attribute where attrelid = 'user_mobile_contact_hashes'::regclass and attisdropped;
attrelid | attname | atttypid | attstattarget | attlen | attnum | attndims | attcacheoff | atttypmod | attbyval | attstorage | attalign | attnotnull | atthasdef | attisdropped | attislocal | attinhcount | attcollation | attacl | attoptions | attfdwoptions

6097850 | ........pg.dropped.10........ | 0 | 0 | 1 | 10 | 0 | -1 | -1 | f | p | c | f | f | t | t | 0 | 0 | | |

when i create this table user_mobile_contact_hashes , the function works well. i try to delete those 2 dropped column info from 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
