BEGIN EXCEPTION END - small bug?

Hi list,

i tried a bit with errorhandling and found the following :
(i want to ignore the dublicate key exception)


CREATE OR REPLACE FUNCTION test() RETURNS VARCHAR AS'
BEGIN BEGIN  INSERT INTO table a dublicate key (primary); EXCEPTION  WHEN OTHERS THEN ROLLBACK; END; RETURN ''test'';
END'LANGUAGE plpgsql;


will result in

ERROR:  SPI_prepare failed for "ROLLBACK": SPI_ERROR_TRANSACTION

I noticed the right syntax would be (works fine)

CREATE OR REPLACE FUNCTION test() RETURNS VARCHAR AS'
BEGIN BEGIN  INSERT INTO table a dublicate key (primary); EXCEPTION  WHEN OTHERS THEN END; RETURN ''test'';
END'LANGUAGE plpgsql;


Just a hint

Regards Daniel
