I am not aware of any OSS geocoding software.
Adding geocoding capabilities to PostGIS would be possible, using some
of the existing postgresql text comparison functions (levenshtien,
soundex, phonex) and one new geometry function to generate the geocoded
points. However, this is not something that is on our "hit parade" of
things to do, yet. (We have one client who has slightly mentioned
wanting this, but no dollar commitment to the development at this
point.)
