+  <para>
+   <command>CREATE USER MAPPING</command> defines a mapping of a user
+   to a foreign server.  A user mapping typically encapsulates
+   connection information that a foreign-data wrapper uses together
+   with the information encapsulated by a foreign server to access an
+   external data resource.
+  </para>
+
+  <para>
+   The owner of a foreign server can create user mappings for that
+   server for any user.  Also, a user can create a user mapping for
+   their own user name if <literal>USAGE</literal> privilege on the server has
+   been granted to the user.

+      server already exists. A notice is issued in this case.  Note that there
+      is no guarantee that the existing user mapping is anything like the one
+      that would have been created.

+      names and values are specific to the server's foreign-data wrapper.
