installation requirements repmgr is developed and tested on Linux and OS X, but should work on any UNIX-like system supported by PostgreSQL itself. There is no support for Microsoft Windows. From version 4.0, repmgr is compatible with all PostgreSQL versions from 9.3. Note that some &repmgr; functionality is not available in PostgreSQL 9.3 and PostgreSQL 9.4. If upgrading from &repmgr; 3.x, please see the section . All servers in the replication cluster must be running the same major version of PostgreSQL, and we recommend that they also run the same minor version. &repmgr; must be installed on each server in the replication cluster. If installing repmgr from packages, the package version must match the PostgreSQL version. If installing from source, &repmgr; must be compiled against the same major version. A dedicated system user for &repmgr; is not required; as many &repmgr; and repmgrd actions require direct access to the PostgreSQL data directory, these commands should be executed by the postgres user. See also Prerequisites for configuration for information on networking requirements. We recommend using a session multiplexer utility such as screen or tmux when performing long-running actions (such as cloning a database) on a remote server - this will ensure the &repmgr; action won't be prematurely terminated if your ssh session to the server is interrupted or closed.
