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.
The most recent
repmgr version (5.2.1) supports all PostgreSQL versions from 9.5 to 13. PostgreSQL 9.4 is also supported, with some restrictions.
repmgr is distributed under the GNU GPL 3 and maintained by EnterpriseDB.
