This sounds like a job better suited to a normal active/standby configuration with regular built-in streaming replication. Use a tool like repmgr to manage failover and a proxy like pgbouncer to redirect traffic.
There's no reason to use async multi-master replication when simple single-master replication will do just as well. -- Craig Ringer http://www.2ndQuadrant.com/
