PostgreSQL + Replication supports asynchronous replication and is designed to be WAN tolerant. It uses a distributed transaction log to keep track of updates produced by the Master database. The system allows for multiple Slaves to receive updates in either a continuous or batch mode.

Features

1. Master to Multi-Slave.
2. Per table replication selection.
3. SSL connectivity between communication processes.

5. Designed to be WAN and congested network tolerant.
6. Batch Mode for updates to off-site locations at off peak hours.
7. Continuous mode for live replication.
8. Combined with Heartbeat, or other fail-over software, it provides a true "in the database" 24/7 capable production environment.
