Right.  Instead of talking in circles, let's figure out how to do it.
If the issue is only sequence numbers, can we force a column to _only_
get values from the sequence counter, thereby makeing the index span
unnecessary?  Can't we look up stuff in parent/child index to check for
collisions before we add a row?  Doesn't seem too hard to me.
