  26.    <code class="command">ALTER ROUTINE</code> changes the definition of a routine, which

  27.    can be an aggregate function, a normal function, or a procedure.  See

  28.    under <a class="xref" href="sql-alteraggregate.html" title="ALTER AGGREGATE"><span class="refentrytitle">ALTER AGGREGATE</span></a>, <a class="xref" href="sql-alterfunction.html" title="ALTER FUNCTION"><span class="refentrytitle">ALTER FUNCTION</span></a>,

  29.    and <a class="xref" href="sql-alterprocedure.html" title="ALTER PROCEDURE"><span class="refentrytitle">ALTER PROCEDURE</span></a> for the description of the

  30.    parameters, more examples, and further details.

  31.   </p></div><div class="refsect1" id="id-1.9.3.27.6"><h2>Examples</h2><p>

  32.    To rename the routine <code class="literal">foo</code> for type

  33.    <code class="type">integer</code> to <code class="literal">foobar</code>:

  34. </p><pre class="programlisting">

  35. ALTER ROUTINE foo(integer) RENAME TO foobar;

  36. </pre><p>

  37.    This command will work independent of whether <code class="literal">foo</code> is an

  38.    aggregate, function, or procedure.

  39.   </p></div><div class="refsect1" id="id-1.9.3.27.7"><h2>Compatibility</h2><p>

  40.    This statement is partially compatible with the <code class="command">ALTER

  41.    ROUTINE</code> statement in the SQL standard.  See

  42.    under <a class="xref" href="sql-alterfunction.html" title="ALTER FUNCTION"><span class="refentrytitle">ALTER FUNCTION</span></a>

  43.    and <a class="xref" href="sql-alterprocedure.html" title="ALTER PROCEDURE"><span class="refentrytitle">ALTER PROCEDURE</span></a> for more details.  Allowing

  44.    routine names to refer to aggregate functions is

  45.    a <span class="productname">PostgreSQL</span> extension.
