  <title>Examples</title>

  <para>
   To rename the procedure <literal>insert_data</literal> with two arguments
   of type <type>integer</type> to <literal>insert_record</literal>:
<programlisting>
ALTER PROCEDURE insert_data(integer, integer) RENAME TO insert_record;
</programlisting>
  </para>

  <para>
   To change the owner of the procedure <literal>insert_data</literal> with
   two arguments of type <type>integer</type> to <literal>joe</literal>:
<programlisting>
ALTER PROCEDURE insert_data(integer, integer) OWNER TO joe;
</programlisting>
  </para>

  <para>
   To change the schema of the procedure <literal>insert_data</literal> with
   two arguments of type <type>integer</type>
   to <literal>accounting</literal>:
<programlisting>
ALTER PROCEDURE insert_data(integer, integer) SET SCHEMA accounting;
</programlisting>
  </para>

  <para>
   To mark the procedure <literal>insert_data(integer, integer)</literal> as
   being dependent on the extension <literal>myext</literal>:
<programlisting>
ALTER PROCEDURE insert_data(integer, integer) DEPENDS ON EXTENSION myext;
</programlisting>
  </para>

  <para>
   To adjust the search path that is automatically set for a procedure:
<programlisting>
ALTER PROCEDURE check_password(text) SET search_path = admin, pg_temp;
</programlisting>
  </para>

  <para>
   To disable automatic setting of <varname>search_path</varname> for a procedure:
<programlisting>
ALTER PROCEDURE check_password(text) RESET search_path;
</programlisting>
   The procedure will now execute with whatever search path is used by its
   caller.

  <title>Compatibility</title>

  <para>
   This statement is partially compatible with the <command>ALTER
   PROCEDURE</command> statement in the SQL standard. The standard allows more
   properties of a procedure to be modified, but does not provide the
   ability to rename a procedure, make a procedure a security definer,
   attach configuration parameter values to a procedure,
   or change the owner, schema, or volatility of a procedure. The standard also
   requires the <literal>RESTRICT</literal> key word, which is optional in
   <productname>PostgreSQL</productname>.
