PostgreSQL version: 7.4.3

Description: standard compilation

Details:

Posiible bug in contrib/intarray package (function idx)

For test I use FoodMart Database from Mondrian Project (mondrian data):
http://sourceforge.net/projects/mondrian/

build table (for rank):

===== BEGIN QUER =====
CREATE TABLE rank_test
(
idx serial NOT NULL,
week_of_year int4,
the_year int4,
rank int4[],
CONSTRAINT rank_test_pkey PRIMARY KEY (idx)
)
WITH OIDS;
===== END QUERY =====

Insert to table rank index of customers:

===== BEGIN QUER =====
INSERT INTO rank_test(week_of_year, the_year, rank)
SELECT t1.week_of_year, t1.the_year, array_accum(t1.customer_id) FROM
(SELECT sum(store_sales*unit_sales), week_of_year, the_year, customer_id
FROM
(
SELECT *
FROM
sales_fact_1997 sf97 LEFT OUTER JOIN time_by_day td ON (sf97.time_id =
td.time_id)
UNION
SELECT *
FROM
sales_fact_1998 sf98 LEFT OUTER JOIN time_by_day td ON (sf98.time_id =
td.time_id)
UNION
SELECT *
FROM
sales_fact_dec_1998 sf98d LEFT OUTER JOIN time_by_day td ON (sf98d.time_id
= td.time_id)
) AS sf_all
GROUP BY week_of_year, the_year, customer_id
ORDER BY the_year, week_of_year, sum, customer_id
) AS t1
GROUP BY t1.week_of_year, t1.the_year
ORDER BY t1.the_year, t1.week_of_year

and when I run:
SELECT idx, idx(rank, 4676), icount(rank) FROM rank_test WHERE 4767 = ANY
(rank)
===== END QUERY =====

I get this:

*** BUG ***
for example in this output idx=11 (idx from rank_test table, 11 row)
function return idx(rank, 4676)=0 ?????? <- here BUG
