That's not a bug; it's operating as designed. If you want more error
checking, don't use to_date() --- just cast the string to date.

regression=# show datestyle;
DateStyle
-----------
ISO, MDY
(1 row)

regression=# select '10-30-2012'::date;
date
------------
2012-10-30
(1 row)

regression=# set datestyle = dmy;
SET
regression=# select '10-30-2012'::date;
ERROR: date/time field value out of range: "10-30-2012"
LINE 1: select '10-30-2012'::date;
^
HINT: Perhaps you need a different "datestyle" setting.
