    Syncing DB defaults with entities is indeed a painful exercise as JDBC
    provides no callback mechanism to let the app know which defaults were
    set. Here is one more brute force mechanism to achieve that -
    invalidate all newly inserted objects. E.g., using 3.0 API:

    List newObjects = context.newObjects();
    context.commitChanges();
    context.performGenericQuery(new RefreshQuery(newObjects));
