 ### Controlling `primary_conninfo` in `recovery.conf`
 
-`repmgr` will create the `primary_conninfo` setting in `recovery.conf` based
-on the connection parameters provided to `repmgr standby clone` and PostgreSQL's
-standard connection defaults, including any environment variables set on the
-local node.
+The `primary_conninfo` setting in `recovery.conf` generated by `repmgr`
+is generated from the following sources, in order of highest to lowest priority:
+
+- the upstream node's `conninfo` setting (as defined in the `repl_nodes` table)
+- the connection parameters provided to `repmgr standby clone`
+- PostgreSQL's standard connection defaults, including any environment variables
+  set on the local node.
 
 To include specific connection parameters other than the standard host, port,
 username and database values (e.g. `sslmode`), include these in a `conninfo`-style
-tring passed to `repmgr` with `-d/--dbname` (see above for details), and/or set
+string passed to `repmgr` with `-d/--dbname` (see above for details), and/or set
 appropriate environment variables.
 
 Note that PostgreSQL will always set explicit defaults for `sslmode` and
 `sslcompression`.
 
+If `application_name` is set in the standby's `conninfo` parameter in
+`repmgr.conf`, this value will be appended to `primary_conninfo`, otherwise
+`repmgr` will set `application_name` to the same value as the `node_name`
+parameter.
