repmgr is a set of open source tools that helps DBAs and System administrators
manage a cluster of PostgreSQL databases.

By taking advantage of the Hot Standby capability introduced in PostgreSQL 9,
repmgr greatly simplifies the process of setting up and managing database with
high availability and scalability requirements.

repmgr simplifies administration and daily management, enhances productivity
and reduces the overall costs of a PostgreSQL cluster by:

* monitoring the replication process;
* allowing DBAs to issue high availability operations such as switch-overs
and fail-overs.
