not sure i agree with "most systems" here - a _LOT_ of use cases
actually want async (and note that slony1 can do a controlled failover
without any transactions lost).

Nevertheless there are also points for having sync-replication but
calling slony1 "insufficient" in that regard is a bit much since it is
actually designed to be async and does quite a good job with that.
