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.
