The first in the list that is actively streaming will be used as the current synchronous server. When this fails, the system fails over to the next in line. Synchronous multi-master replication is not included in the PostgreSQL core. Postgres-XC which is based on PostgreSQL provides scalable synchronous multi-master replication. [38]
