If entity-handle is local (on local part/proc.) then one can ask such
questions (ghost entity etc.), but if entity is not local, i.e,
remote-handle or remote-copt then it is not valid to ask such questions.
How do we return reasonable error message/code in this case of
remote-handle. There are no globally unique entity handles.

I do not see why these will be expensive, at least they are not in FMDB
implementation.
