Well, you have to put the tablespace on a mount point that's not
otherwise used by Postgres, but beyond that I don't see the problem.

The point here is not that it's amazingly simple or convenient to use;
obviously it isn't.  The point is that it's *possible* to get this sort
of effect today, and so we have to ask whether it's really worth a good
deal of development effort and code complexity to provide somewhat
more convenient, but basically duplicate, functionality within Postgres.
