[turba] Using horde-db-migration script to update schema

[John H. Bennett III]

Hello,

I need to add a column to the turba_objects table.  I can create a  
migration script and place it in the turba/migration directory, and it  
will execute just fine and do what I need, but that will then result  
in install getting out of sync with the official turba schema.  Plus,  
I learned all of the specific migration files must have unique  
numerical values, or the schema upgrades will fail to run.   Is there  
a way for a general admin to use the horde-db-migration script to add  
columns or other items, or must I find a different way to add things?

Thank you,

John
