Common Lisp vs Clojure for web apps?
wglb: Clojure seems likely to be able to plug into whatever Java libraries you might want to use. CL (in particular, SBCL) is used to power a number of web sites and they use Lisp all the way down.  One of my favorites is http://wigflip.com/ that has a number of fun toys.  Weblocks is a good CL framework.  and there is support for Posgtress (as well as mysql, etc etc) available for CL.Check those out for that side of what you can do with CL.I am less familiar with the Java world, but Clojure seems to be very capable in that area.
