It would seem that your contact_date field isn't actually a date field. You probably need to use:

extract(month from (contact_date::date))

Made the above answer complete.

SELECT EXTRACT(MONTH FROM ('17NOV2011' :: DATE)) AS MONTH_NUMBER

In case the date cast doesn't work you can control it with to_date

select extract(MONTH FROM to_date('05DEC2010','DDMonYYYY'))

Also Works

select date_part('Month',to_date('05DEC2010','DDMonYYYY'))

Also Works

select to_char(to_date('05DEC2010','DDMonYYYY'),'MM')

You can use select month('05DEC2010') as a simpler and more efficient way!
