Sorry, I dont understand clearly. I do understand that pickle saves only __dict__ when no __getstate__ defined. So, to be cached, an object should fetch all its deferred columns (if any) and provide all of them at __getstate__. Right? And if an instance from cache has nothing for one of its deferred column values, then referencing these properties after merge wont load them from DB, but just fail?
