    Exactly. Problem is that Derby is a bit annoying in that you can't
    alter columns in very many ways. Can't even make a non-null field
    into one allowing nulls. So updates take the form of:

    - create new column
    - copy data
    - delete old column

    Of course all this runs before Cayenne gets initialised.
