Trigger (Calling a Procedure) - Mailing list pgsql-general

Hi,

I'm trying to create a trigger with the following definition:

CREATE TRIGGER insert_price_change AFTER INSERT OR DELETE OR UPDATE ON raw_email
  FOR EACH ROW EXECUTE PROCEDURE add_one(1);

Procedure / Function add_one has the following definition

CREATE FUNCTION add_one(integer) RETURNS integer
     AS '/usr/local/pgsql/jsb/add_one', 'add_one'
     LANGUAGE C STRICT;

function add_one is running fine.

When I try to create the trigger insert_price_change, it throws me the follwoing error:

ERROR:  function add_one() does not exist

However, I can see function add_one(int4) as one of the functions in  pgadmin.

Don't know whats going on wrong.

Thanks,

~Harpreet
