ok, ok, Marc... you've got me into it now... :)

I started thinking about that talking to Marc about the CORBA ORB issue.
GNOME wants ORBit, BSD'ers want mico, linux'ers want omniorb, etc...
(forgive any possible generalizations above)

Basically what I was saying to Marc is that the really ORB-dependent part
of CORBA is the IDL-to-<language> mappings. The logic of the CORBA object
can be implemented as a normal object independent of the compiled stub.
Then, all that has to be done is to fill in the stubs with code that
acts as an adaptor to the ORB-independent object. That way porting to
another ORB should be trivial.

Someone out there correct me if I'm wrong... :)

I do like the idea of using CORBA to access postgreSQL. There is the
obvious advantage of not having to worry about porting libpg to every
system and language. CORBA ORB vendors/developers can take care of that.

What really makes me curious is what the object's interface will be...
Just a clone of libpg, or something more?... I think someone earlier
mentioned possibly doing things like directly referencing "objects."
I think that the use of CORBA could allow for much more functionality
than a classical SQL RDBMS interface. I don't know that much about the
backend, but it could be interesting to throw some ideas back and forth
about what could be done with the interface.

I would personally prefer to have a more natural OO interface to
the database, possibly expanding on the idea of being able to directly
reference objects (and hold the reference to them).
