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.


The full repmgr documentation is available here:

The old README file for repmgr 3.x is available here:

Note that the repmgr 3.x series is no longer supported and contains known bugs; please upgrade to the current repmgr version as soon as possible.


For an overview of repmgr versions and PostgreSQL compatibility, see the repmgr compatibility matrix.
