Well, actually, there's a reason why pg_upgrade isn't in the CVS tree
anymore ... it never quite worked and for many releases has been in
absolutely no danger of working.  So you've not exactly allayed my
concerns by stating the above.  I suggest again that you ought to be
running your basic design past the list sooner rather than later.
There are a lot of smart people on this list --- they can help you
not make mistakes.
