I'm not sure if this is a bug, or not - but it looks like one to me.
if you say:
CREATE TABLE testtable (
col1 char(1),
data text
);
INSERT INTO testtable (col1, data) VALUES ('1', 'foobar');
INSERT INTO testtable (col1, data) VALUES ('2', 'foobarbaz');
The following queries all work:
INSERT INTO testtable (col1, data) VALUES (3::int, 'foobarbazquux');
SELECT * FROM testtable WHERE col1 = 3::int;
SELECT * FROM testtable WHERE col1 IN (1);
SELECT * FROM testtable WHERE col1 IN (1::int);
However these querys fail on 8.2.4, but work correctly on 8.1:
SELECT * FROM testtable WHERE col1 IN (1::int, 2::int);
SELECT * FROM testtable WHERE col1 IN (1, 2);
I could understand if the behavior was the same for single element IN
clauses, and multiple element IN clauses - however as their behavior
is different, and it used to work in 8.1....
Cheers
