I don't use the peqdatabase\updates directory, so I could be completely wrong, but it appears that if you only update your source code when there is a new PEQ release and always match it exactly then those updates should keep your database schema in sync. 
 
The updates that are in the source code directory I mentioned above will do the same, and in this case would have given you the new AA data where just using the PEQ updates without sourcing a completely new database would not.
