José María Fernández González (jmfernandez@cnb.uam.es) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
PL/pgSQL triggers with parameters don't work
Long Description
The report is for PostgreSQL 7.1.2. When you create a trigger which calls a function with parameters, the system
linksagainst the function with the same name and no parameter, and if it doesn't exist it tells "function doesn't
exist".Tests have been made with PL/pgSQL-encoded functions.
Sample Code
CREATE table a(
b INTEGER,
c TEXT
);
CREATE FUNCTION cascaya (INTEGER) RETURNS OPAQUE AS '
DECLARE
value ALIAS FOR $1;
BEGIN
IF value > 0
THEN
RAISE EXCEPTION ''Value: %'',value;
END IF;
return NULL;
END;
' LANGUAGE 'plpgsql';
CREATE TRIGGER case1 BEFORE INSERT
ON a FOR EACH ROW
EXECUTE PROCEDURE cascaya(5);
ERROR: CreateTrigger: function cascaya() does not exist
CREATE FUNCTION cascaya () RETURNS OPAQUE AS '
BEGIN
return NULL;
END;
' LANGUAGE 'plpgsql';
CREATE TRIGGER case2 BEFORE INSERT
ON a FOR EACH ROW
EXECUTE PROCEDURE cascaya(5);
select proname,pronargs,oid from pg_proc where proname='cascaya';
proname | pronargs | oid
---------+----------+---------
cascaya | 0 | 1050555
cascaya | 1 | 1050554
select tgname,tgfoid,tgnargs from pg_trigger where tgname='case2';
tgname | tgfoid | tgnargs
--------+---------+---------
case2 | 1050555 | 1
