Hmm. I guess we could enumerate the pg_tblspc directory, and call
readlink() on all the symlinks in there. Assuming all platforms can do
readlink() (we'd obviously need a special windows implementation,  but
that's doable I guess).

I just figured it'd be a lot cleaner to read it from our own catalogs...
