pg_dump will never depend on any such thing anyway.  It has too many
special-purpose requirements, like needing to split up object
definitions in particular ways, cope with very old server versions,
etc etc.  Insisting that this feature support pg_dump is a good way
of making sure that nothing useful will emerge at all.

Maybe we could replace (some of) psql's describe.c logic with
server-side code, but I'm skeptical that there'd be much win
there either.

So I don't really buy Álvaro's argument above.  It'd be better
to design to some concrete requirement that isn't either of
those.  Unfortunately, it's not clear to me that anyone has
a concrete use-case in mind that isn't either of those.
