I'm not sure I follow this. We would be looking to the ORB to replace
*all* on-the-wire communications between frontends and backends, to take
advantage of the data marshalling, security and directory layers of
Corba. So we would want the ORB to infest at least parts of the current
Postgres backend to eliminate the current socket/IP interface, right?

Or would we only be using the ORB to present a sort-of-thin client
layer, to replace libpq for an app? Are there other RDBMSes which claim
to have a Corba interface? What does the API look like?

I've been looking at Corba for other projects, and have worked with DCE
a bit in the past. I would guess that the interface between, say, psql
and a server would have psql asking for a postgres server through the
corba API, and the server side would provide a fresh backend as a
result. The API would include methods to allow queries, etc, and methods
to return results...
