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 (5.3.2) supports all PostgreSQL versions from
9.5 to 15. PostgreSQL 9.4 is also supported, with some restrictions.

`repmgr` is distributed under the GNU GPL 3 and maintained by EnterpriseDB.
