(I haven't seen the original message yet, so I'm replying to a reply)
Date literals are generally written as:
DATE '1/11/2003'
PostgreSQL will try to guess what type you meant with quoted strings in
expressions, but in the above there isn't enough context to do guess that
you meant a date really (it should probably actually be thought of as a
string in such cases).
