to_date problem

Hello,

  I have just observed the following problem:

-------------------------------------------------------------------
testdb=# select to_date('2001-3-5 10:00', 'YYYY-MM-DD HH24:MI') from dual;
  to_date
------------
 2001-03-10
(1 row)

testdb=# \q
[nsadmin@ljserv calendar]$ psql --version
psql (PostgreSQL) 7.1beta3
contains readline, history support

-------------------------------------------------------------------

   I know that the date constant is not in the same format as the format
string, but shouldn't it be an error rather than 'just' returning a
wrong date?

    Any suggestions,
