I don't believe there is, or can be, any asynchronous multi-master
replication system for any database that will work with all possible
general purpose constructs.
Given that, you might need to be more specific about your
needs (and rethink your application architecture based on the
reality of the issue), unless the constraints of synchronous
replication work for you particular problem space.
