I think I agree.  The current behavior would have made sense in older
releases of PG where we plopped down our stuff right inside the
tablespace directory, but now that everything is being shoved in a
subdirectory I don't see a reason to copy anything other than that
subdirectory.  Of course it's probably bad style to have anything
that's not related to PG in there, but given that the whole point of
this change was to allow different PG versions to create tablespaces
on the same directory at the same time, we can hardly say that this is
a case that should never arise in real life.

Makes sense, yeah. Of course, anything stuffed *inside* said subdir
will still be included, but that's violating that principle even more
:)
