Hello,
re-testing our application Openbravo on 9.6beta2 i found the following query
failing to run with
ERROR: cache lookup failed for type 0
Tested on 9.6beta2
Specifically debian package version '9.6~beta2-1.pgdg+1' from
apt.postgresql.org
SELECT
SUM(C_ORDERLINE.LINENETAMT),
C_CURRENCY_SYMBOL2 (SUM(C_ORDERLINE.LINENETAMT))
FROM C_ORDER, C_ORDERLINE
WHERE C_ORDER.C_ORDER_ID = C_ORDERLINE.C_ORDER_ID
GROUP BY C_ORDER.DOCUMENTNO
ORDER BY C_ORDER.DOCUMENTNO;
Note: query is slimmed down manually which still reproduces the issue (cut down
from biggger query), which explain the kind of (now)(now) useless pl-function.
To reproduce in new empty database:
CREATE OR REPLACE FUNCTION public.c_currency_symbol2(p_amount numeric)
RETURNS character varying AS
$BODY$ DECLARE
BEGIN
RETURN p_amount;
END ; $BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
create table c_order (c_order_id varchar(32) primary key, documentno
varchar(60));
create table c_orderline (c_orderline_id varchar(32) primary key, c_order_id
varchar(32), linenetamt numeric, c_currency_id varchar(32));
Deleting any more out of the query seems to no longer trigger the problem.
Also changing the 'c_orderline' create table statement to not have the last
column 'c_currency_id' (which is not even referenced in the query) also makes
the issue no longer reproducible.
Regards,
Stefan
