This script will crash the connection

Helo all,

Please try this script, it will crash the current connection.
I'm using the 01/18/2001 PostgreSQL v7.1 beta3 snapshot.

-- Script begin -------------------------------------
create table blah(
var_field varchar(8),
n1 integer default 23,
n2 integer,
arr_str varchar[],
m money,
s text
);

create rule blah_update as
on update to blah
do
notify TestEvent;

INSERT INTO blah (var_field, n1, n2, arr_str, m, s) VALUES ('aaa', 1, 2,
NULL, NULL, NULL);
UPDATE blah SET n1=n1+1; -- Won't crash the connection
UPDATE blah SET n1=2 WHERE var_field='aaa' AND n1=1 AND n2=2 AND arr_str IS
NULL AND m IS NULL; -- Will crash the connection

-- Script end -------------------------------------
psql will print :

pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

Any comments ?

I need this kind of code working for a demo for ZeosDBO users...
