I think one needs to be careful not to overstate the success achieved.  It
does work.  That doesn't mean it's easy or quick.  Given that TheirSQL
drops
the new daemon in place and upgrades the tables on the way by, upgrade via
Slony looks remarkably kludgey.

Yes, I understand the reasons why it's this way; that doesn't mean it's
the
best of all possible worlds.  Dr Pangloss was wrong, durnit.
