DROP_USER_MAPPING - remove a user mapping for a foreign server

DROPUSERMAPPING conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a PostgreSQL extension.

DROPUSERMAPPING removes an existing user mapping from foreign server.

       The owner of a foreign server can drop user mappings for that server for any user. Also, a user can drop
       a user mapping for their own user name if USAGE privilege on the server has been granted to the user.

       Drop a user mapping bob, server foo if it exists:

           DROP USER MAPPING IF EXISTS FOR bob SERVER foo;

       IF EXISTS
           Do not throw an error if the user mapping does not exist. A notice is issued in this case.

       user_name
           User name of the mapping.  CURRENT_ROLE, CURRENT_USER, and USER match the name of the current user.
           PUBLIC is used to match all present and future user names in the system.

       server_name
           Server name of the user mapping.
