Encapsulation is almost always preferable, but I don't think Tatsuo was
saying otherwise, merely pointing out a clever trick that I hadn't
though of (I didn't realize that "/foo" would be rooted rather than
just put under PGDATA, in fact I stay away from quoted non-SQL non-"normal
language" identifiers altogether, being somewhat interested in portability
of my application code).

And it is a clever trick...obvious to an insider, but not to me.

I think the decision to keep the mechanism for providing separate
storage mangers was a good one (if I understand correctly that there
was once consideration of removing it).  Even if it is never used in
mainstream Postgres, some specialty application may use it, one of
the potentials that comes from open source software.
