+ <code class="command">CREATE USER MAPPING</code> 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.
+ </p><p>
+ 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 <code class="literal">USAGE</code> privilege on the server has
+ been granted to the user.

+ Do not throw an error if a mapping of the given user to the given foreign
+ 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

+ </p></dd><dt><span class="term"><em class="replaceable"><code>user_name</code></em></span></dt><dd><p>
+ The name of an existing user that is mapped to foreign server.
+ <code class="literal">CURRENT_ROLE</code>, <code class="literal">CURRENT_USER</code>, and <code class="literal">USER</code> match the name of
+ the current user. When <code class="literal">PUBLIC</code> is specified, a
+ so-called public mapping is created that is used when no

+ This clause specifies the options of the user mapping. The
