OK, I agree, but I still think a lot of DBAs would have no idea how to
handle that situation. I agree with your proposal, don't get me wrong
- I just think there's still an awful lot of room for operator error
in these more complex replication scenarios. I don't have a clue how
to fix that, and it's certainly not the purpose of this thread to fix
that; I'm just venting.

Actually, I'm really glad to see all the work you've done to improve
the way that some of these scenarios work and eliminate various bugs
and other surprising failure modes over the last couple of months.
It's great stuff. Alas, I think we still some distance from being
able to provide an "easy button".
