I'm trying to validate a day of the week, and thought that to_date would
do the job for me. But I found a case where it cannot tell the
difference between sunday and monday. Is this a bug or intended
behaviour?
dev=# select to_date('2011-13-Mon', 'YYYY-IW-DY');
to_date
------------
2011-03-28
(1 row)
dev=# select to_date('2011-13-Sun', 'YYYY-IW-DY');
to_date
------------
2011-03-28
(1 row)
dev=# select to_date('2011-13-Tue', 'YYYY-IW-DY');
to_date
------------
2011-03-29
(1 row)
This is on postgres 8.3.14.
