IMHO, There has no ideal ORB for all platforms.
we use ORBacus (http://www.ooc.com),
because it's the only known for me ORB, working without threads
so its really faster and more stable than another ones under FreeBSD,
but it's not free.

May be it is better make directory CORBA under interfaces subtree
and time-to-time put objects for differend ORB's inside,
into separate directory.

Probably, It's better to make separate configure for
some parts of postgres distributions to allow users to build/upgrade
parts of postgres i.e psql or perl interface
