What day is it - when it isn't NOW()?

Hi,

SELECT to_char(now(), 'Day');  returns Friday as I'd hoped.
But how do I return the day of the week for a specific date other
than now()?  I'm looking for something along the lines of:
SELECT to_char('2003-08-04', 'Day') without much success.

Can anyone point me to the right function/combination of functions
to achieve this?

Thanks!
