This has already been implemented:


It is not yet documented in the manual, but the basic usage is:

#pragma db object
class obj1
  #pragma db id
  int id;


#pragma db object
class obj2

  #pragma db points_to(obj1)
  int o1;

Note also that in your case you may also consider lazy object pointers. You
could just unload all the pointer before passing things to another thread.
