That might be a way forward, but for someone who doesn't use tablespaces
and just wants and all-on-one backup, this change would make that more
cumbersome, because now you'd always have more than one file to deal with.
It might be worth considering a mode that combines all those tar files
into a super-tar. I'm personally not a user of the tar mode, so I don't
know what a typical use would be, though.
