   3    The view <code class="literal">routine_routine_usage</code> identifies all functions
   4    or procedures that are used by another (or the same) function or procedure,
   5    either in the SQL body or in parameter default expressions.  (This only
   6    works for unquoted SQL bodies, not quoted bodies or functions in other
   7    languages.)  An entry is included here only if the used function is owned
   8    by a currently enabled role.  (There is no such restriction on the using
   9    function.)
  10   </p><p>
  11    Note that the entries for both functions in the view refer to the
  12    <span class="quote">“<span class="quote">specific</span>”</span> name of the routine, even though the column names
  13    are used in a way that is inconsistent with other information schema views
  14    about routines.  This is per SQL standard, although it is arguably a
  15    misdesign.  See <a class="xref" href="infoschema-routines.html" title="35.45. routines">Section 35.45</a> for more information
  16    about specific names.
