PostgreSQL is one of the most advanced open source databases available, and has an enviable track record in performance, standards compliance, features, security, reliability and ACID compliance.

SteelEye's LifeKeeper provides the ability for business critical processes to be deployed on PostgreSQL, where downtime is expensive and has to be minimised.

LifeKeeper is a non-intrusive solution for High Availability Clustering, and does not require modification to the application

LifeKeeper is able to monitor all resources used by PostgreSQL (IP, Disk, File System) as well as checking that PostgreSQL itself is running (for example it could execute a known SQL query). This proactive approach allows LifeKeeper to initiate a failover to a different node in the cluster regardless of whether the fault was software related (O/S, Application etc) or hardware related (disk, network etc).
