It seems that you want to do data analysis, i think that R could do
whatever you want. For clustering, as shown on index page of the web
site you can build ACP clusters and factorial analysis. But R is not
easy to use. You can connect R to postgis (as you can connect it to a
lot of databases), and i think that you can use PostGIS features from R.
