Using rule with function for view delete gives error on OLD.* type

Hi,

Can anyone explain or suggest a workaround for the following:

I am getting the error:

"ERROR: record type has not been registered"
CONTEXT: PL/pgSQL function "f_cmplx_prdct_dlte" while storing call
arguments into local variables

when I call a function from a delete rule for a view I've created.

The view has 42 fields.

Selecting from the view works OK, and inserting using an insert function
called from the insert rule using new.* works OK.

A delete function called from the delete rule using old.* gives the error
above.

The type seems to be in the database correctly.

I have another similar view, using 45 fields (most of them the same!)
with a delete rule and function that works OK.

I have tried deleting and re-creating the view and its associated
functions, the error did not change.

I get the same error even if the delete function contents are blank

The rule that fails is:

CREATE OR REPLACE RULE rle_cmplx_prdct_dlte AS
ON DELETE TO complex_product DO INSTEAD SELECT
f_cmplx_prdct_dlte(old.*) AS f_cmplx_prdct_dlte;

The function it calls starts as follows (it fails before the 'raise
warning'):

CREATE OR REPLACE FUNCTION
bsns_obj.f_cmplx_prdct_dlte(bsns_obj.complex_product)
RETURNS void AS
$BODY$

DECLARE
oldrst ALIAS FOR $1;

fn varchar;

FnResult varchar;
intResult integer;
BEGIN
raise warning 'Start of f_cmplx_prdct_dlte';

I am using a Postgres 8 server on Windows 2000, my client is running on
Windows XP.

Thanks,

Christine.
