configuration prerequisites Following software must be installed on both servers: PostgreSQL repmgr At network level, connections between the PostgreSQL port (default: 5432) must be possible between all nodes. Optionally, if you want repmgr to copy PostgreSQL configuration files which are located outside the data directory (as is the case with e.g. Debian packages) when cloning a standby, or use &repmgr; to perform switchovers, passwordless SSH connections are required between all nodes. Additionally, for copying files outide the data directory, rsync must be installed. &configuration-file; &configuration-file-required-settings; &configuration-file-log-settings; &configuration-file-service-commands; configuration database user permissions &repmgr; will create an extension database containing objects for administering &repmgr; metadata. The user defined in the conninfo setting must be able to access all objects. Additionally, superuser permissions are required to install the &repmgr; extension. The easiest way to do this is create the &repmgr; user as a superuser, however if this is not desirable, the &repmgr; user can be created as a normal user and a superuser specified with --superuser when registering a &repmgr; node.
