I don't think it's a reasonable request.  If we take this seriously,
we'd have to buy into making sure that no subdirectory of $PGDATA is
ever empty.  Which is silly.  And what of empty directories elsewhere?
There are any number of ways to shoot yourself in the foot with a bad
choice of tablespace location --- I don't find this one more dangerous
than any other.
