User defined exceptions

Hello all!<br /> Trying to emulate "named" user defined exception with:<br /> CREATE OR REPLACE FUNCTION exception_aaa
() RETURNS text AS $body$<br /> BEGIN<br />    return 31234;      <br /> END;<br /> $body$<br /> LANGUAGE PLPGSQL<br />
SECURITYDEFINER<br /> ;<br /><br /> do $$<br /> begin<br />    raise exception using errcode=exception_aaa();<br />
exception<br />    when  sqlstate exception_aaa()<br />    then<br />       raise notice 'got exception %',sqlstate;<br
/>end;<br /> $$<br />  <br /> Got:<br /><br /> ERROR:  syntax error at or near "exception_aaa"<br /> LINE 20: sqlstate
exception_aaa()<br/><br /> I looks like "when  sqlstate exception_aaa()" doesn't work. <br /><br /> How can I catch
exceptionin this case?<br /><pre class="moz-signature" cols="72">--
