Slony-II will probably need some additional features. But I consider it 
a sign for an immature design not to be able to define those features in 
form of an API and instead starting to hack together a prototype inside 
of the backend that later down the road will get promoted to a solution 
because there never will be any time to turn the findings of that 
explore-phase into a design and develop according to that.
