Let me put it this way. Unix tools like tar can already use symlinks,
as can administrators from the command line, so symlinks are best on
that platform, period.

If we have a platform that doesn't have symlinks (and I think Win32
might), we will have to implement a different way to do tablespace
lookups _only_ for those platforms.

The use of symlinks on Unix has just too many advantages to use a
another sub-optimal solution on that platform.
