This is pilot error isn't it?  It's certainly hard to see what would be
the value of making a tablespace pointing at the data directory itself.

Offhand, I think we do not support tablespaces that are physically inside
the data directory, either.

I think there's been some discussion of having CREATE TABLESPACE try to
detect and reject such cases.  But it would be easy enough to fool it
(through symlinks, variant path spellings, etc), that people haven't been
excited about adding such a check.
