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
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.
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
repmgr 4 will support future public BDR releases.
