Separate issue. Putting the segment number into the filename is
a bad idea because it doesn't give you any way to spread multiple
segments of a big table across filesystems. What's currently being
discussed is paths that look like
something/SEGNO/RELATIONOID.VERSIONID
This lets you control space allocation by making the SEGNO
subdirectories be symlinks to various places.
