data-mining

Hello all, I was woundering  if postgresql would be able to handle
data-mining and data-warehousing concepts.  I have a project for class
in which I have to get at least two rules of data-mining working.  If
anyone has done this with postgresql, please point me in the right
direction.   Would I need additional software or just use the features
of postgresql?  Also could anyone point me in the right direction so I a
large data set to use with data-mining?

Thanks if anyone can help :-)
