The containers and relationships features are orthogonal, you should
be able to use a container to store pointers to objects without doing
anything special.

Well, this looks more like a specialized container that implicitly
stores its elements as shared_ptr's. But I think you should still
be able to use it with ODB. Just make sure that value_type in the
container_traits specialization is shared_ptr<T>, not just T.
