We haven't been able to build production-grade multi-master replication without the barrier of a "standard" database-agnostic API, so I kinda doubt that it will work all that much better with one. See Slony-II. In short the burden of proof is to show why this should go in, not why not. (Suitable proof would be a usable replication system built atop it...) regards, tom lane
