I'm trying to validate a day of the week, and thought that to_date would

dev=# select to_date('2011-13-Mon', 'YYYY-IW-DY');
to_date

Based on running the queries in 9.0, it's behavior that has been corrected:
select to_date('Mon1-13-Tue', 'YYYY-IW-DY');
ERROR: invalid combination of date conventions
HINT: Do not mix Gregorian and ISO week date conventions in a
formatting template.
