Umm...
geometries I use with Postgis & Spatialite - I don't have a database without
them.
Can anyone come up with a data domain for which location has no relevance?
I used to think I had some (like taxonomies & dictionaries), but I've been
corrected in each case :-)
also IP addresses

That's an interesting aside. It would make an interesting OT thread,
if you're inclined to start it. ;-)
I've always thought user-defined types were unnecessary except as a
convenience. There are few new primitive types; most user-defined
types I can think of are "structures" -- sets of columns -- that one
might like to name and constrain as a new type that may appear in many
tables. About the only primitive type I can imagine are mathematical:
complex numbers or exact numeric representations.
