Formatting a month in query output

Hi!

I have a query which needs to provide a monthly report. Thanks to the
date_trunc() function someone mentioned in a thread earlier today, I got
the query working properly. However, each month is '2004-10-01 00:00:00'
and I would like to have "October 2004".

Which function, if any, would help me do this formatting trick? And
where can I read more about it? Or must I use a PHP case statement in
the web page to do this reformatting manually?

Thanks,
