It's used to invoke the "fast path" function call code
(src/backend/tcop/fastpath.c).  libpq's large-object routines use this,
but little else does AFAIK.  The current protocol is sufficiently broken
(see comments in fastpath.c) that I'd not really encourage people to use
it until we can fix it --- hopefully that will happen in 7.4.

PS: what in the world is npgsql-general@gborg.postgresql.org ... is that
a real mailing list, and if so why?  It sounds a bit, um, duplicative.
