As the last person to do any significant work on the eRServer code (at
least the
open-source version), I would have to agree that Slony is the direction
to
take looking forward. I would like to think we managed to fix a lot of
problems, and
improved the usability of it quite a bit, but Andrew Sullivan and I
agreed that its a dead
end - there will be a final packaging of what's in CVS and that will be
it, unless someone else
wants to pick it up.
