Another check: does specifying replication by server in such detail mean
we can't specify robustness at the transaction level? If we gave up that
feature, it would be a greatloss for performance tuning.

It's orthagonal. The kinds of configurations we're talking about simply define what it will mean when you commit a transaction "with synch".

However, I think we're getting way the heck away from how far we really want to go for 9.1. Can I point out to people that synch rep is going to involve a fair bit of testing and debugging, and that maybe we don't want to try to implement The World's Most Configurable Standby Spec as a first step?
