SQL Triggers

Is this an error on my part or is there a bug in the CREATE TRIGGER
code?

darcy=> CREATE FUNCTION function_dead(int)
darcy->     RETURNS int   
darcy->     AS 'UPDATE bid SET live = \'f\' WHERE item_id = $1;     
darcy'>         SELECT 1 AS ignore_this'
darcy->     LANGUAGE 'sql';
CREATE
darcy=> CREATE TRIGGER trigger_dead BEFORE INSERT OR UPDATE
darcy->     ON bid
darcy->     FOR EACH ROW
darcy->     EXECUTE PROCEDURE function_dead (item_id);  
ERROR:  CreateTrigger: function function_dead () does not exist
darcy=> SELECT function_dead(1);
function_dead
-------------
            1
(1 row)

darcy=> DROP FUNCTION function_dead(int);
DROP
darcy=> 

Note that the CREATE FUNCTION works as it can be used as in the SELECT
and it can be dropped proving (?) that it existed.  I think I have
all the argument types right.  I tried it with int4 as well.
