PostgreSQL master to multiple replicas replication system

Slony-I is enterprise-level “master to multiple slaves” replication system with cascading and failover.

The big picture for the development of Slony-I is to build a master-slave system that includes all features and capabilities needed to replicate large databases to a reasonably limited number of slave systems.

Slony-I is developed as a system for data centers and backup sites, where the normal mode of operation is that all nodes are available.

Differences from 1.2 stream

  • Removal of TABLE ADD KEY

  • It drops all support for databases prior to PostgreSQL version 8.3.
