Multi-master replication (MMR) is not supported by PostgreSQL, but there are some commercial tools for it. For example, BDR is a commercial replication system from EnterpriseDB. However, if you are looking for an async multi-master replication tool, then you can try the bucardo tool. There is a new MMR tool called pgEdge, which also an alternative to BDR.
Does PostgreSQL support multi-master replication (MMR)?
