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.
