It doesn't buy you linear scaling in performance, because of the WAL
issues you metioned.  But because index creation is also sort-heavy,
it's still a big help.  Chris and I know this from experience,
because we used this very strategy (his proposal, I note) in
importing the .org database.  I mentioned this approach at OSCON last
