Indeed, that doesn't directly answer the question, but I think the
implication is clear: we do not expect a tablespace directory to
contain anything except files that Postgres itself puts there.

I don't actually see the point of the described setup anyway. There
is zero value that I can see in putting two tablespaces on the same
physical volume --- they won't provide any interesting separation.
