You could use VALUES in a table expression, like this:

    SELECT t1.ID AS SurplusID,
           t1.Name AS SurplusName,
           t2.ID AS MissingID,
           t2.Name AS MissingName
      FROM (VALUES
              (1, 'FOO'),
              (2, 'bar')
           ) AS t1(id, name)
       FULL OUTER JOIN (VALUES (1, 'Z'), (4, 'E'), (7, 'L'))  AS t2 (ID, Name)
      USING (ID, Name)
      WHERE t1.ID IS NULL OR t2.ID IS NULL;
