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.

repmgr 4 is a complete rewrite of the existing repmgr codebase, allowing the use of all of the latest features in PostgreSQL replication.

PostgreSQL 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.

BDR support

repmgr 4 supports monitoring of a two-node BDR 2.0 cluster on PostgreSQL 9.6 only. Note that BDR 2.0 is not publicly available; please contact 2ndQuadrant for details. repmgr 4 will support future public BDR releases.
