Thanks for the thoughts.  I have to say that I have no intention of
reworking the jsonb code.  If somebody else wants to do the legwork and
add that API as you suggest, I'm happy to remove all the ObjTree stuff
from this patch.  I don't expect this to happen too soon, though, so I
would instead consider committing this patch based on ObjTree.  Later,
when somebody comes around to reworking jsonb, we can rip ObjTree out.

Honestly, I had hoped that the jsonb code would have already included
this kind of functionality.  I wasn't too happy when I discovered that I
needed to keep the ObjTree crap.  But I don't want to do that work
myself.
