While upgrading to 0.8.5 I have applied the patch to "Fix incorrect SQL column name in Amavisd database" but this the output of my operation:

mysql> USE amavisd;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> ALTER TABLE policy CHANGE unchecked_lovers_maps unchecked_lover CHAR(1) DEFAULT NULL;
ERROR 1054 (42S22): Unknown column 'unchecked_lovers_maps' in 'policy'
mysql> exit
Bye

I have just updated amavisd-new from 2.6.4-3 to 2.8.0-1 using yum and dag repo.
Attached to this post the amavisd.conf file and the print of policy table.

Thanks for your collaboration,
Cocco
