Hi

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

It is little bit strange - I don't remember any related change in this area.

<blockquote>

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.6........ | 0 | 0 | 8 | 6 | 0 | -1 | -1 | f | p | d | f | f | t | t | 0 | 0 | | |
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.

It is most bad idea! Newer delete anything from system tables. Now, the system catalogue is broken.

The correct fix for first issue is a VACUUM FULL. Second issue - you can try drop table and recreate it,
