The GraphDatabase class in the neo4j Python library is extended behind the scenes the first time it is instantiated, this is what enables the backend to be loaded lazily. This has the side effect that it's not possible to create your own subclasses of it.
I could probably modify it to work with subclasses, but I don't really see a use case for that. Wouldn't it be easier and cleaner for you to implement your added functionality as a wrapping library?
