</pre></div><div class="refsect1" id="id-1.9.3.27.5"><h2>Description</h2><p>
<code class="command">ALTER ROUTINE</code> changes the definition of a routine, which
can be an aggregate function, a normal function, or a procedure. See
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>,
and <a class="xref" href="sql-alterprocedure.html" title="ALTER PROCEDURE"><span class="refentrytitle">ALTER PROCEDURE</span></a> for the description of the
parameters, more examples, and further details.
</p></div><div class="refsect1" id="id-1.9.3.27.6"><h2>Examples</h2><p>
To rename the routine <code class="literal">foo</code> for type
<code class="type">integer</code> to <code class="literal">foobar</code>:
</p><pre class="programlisting">
ALTER ROUTINE foo(integer) RENAME TO foobar;
</pre><p>
This command will work independent of whether <code class="literal">foo</code> is an
aggregate, function, or procedure.
</p></div><div class="refsect1" id="id-1.9.3.27.7"><h2>Compatibility</h2><p>
This statement is partially compatible with the <code class="command">ALTER
ROUTINE</code> statement in the SQL standard. See
under <a class="xref" href="sql-alterfunction.html" title="ALTER FUNCTION"><span class="refentrytitle">ALTER FUNCTION</span></a>
and <a class="xref" href="sql-alterprocedure.html" title="ALTER PROCEDURE"><span class="refentrytitle">ALTER PROCEDURE</span></a> for more details. Allowing
routine names to refer to aggregate functions is
a <span class="productname">PostgreSQL</span> extension.
