This has already been implemented:

https://git.codesynthesis.com/cgit/odb/odb/commit/?id=e78db08d98d5adb4dee3006eea8c3569e383c562

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.
