repmgr: Replication Manager for PostgreSQL
repmgr is a suite of open-source tools to manage replication and failover
within a cluster of PostgreSQL servers. It enhances PostgreSQL's built-in
replication capabilities with utilities to set up standby servers, monitor
replication, and perform administrative tasks such as failover or switchover
operations.
PostgreSQL 12, 11, 10, 9.6 and 9.5 are fully supported.
PostgreSQL 9.4 and 9.3 are supported, with some restrictions.
repmgr is distributed under the GNU GPL 3 and maintained by 2ndQuadrant.
