As I am sure many of you are aware, PostGIS has finally released Version 2.0 and included within this version they have also built a geocoder (see: http://postgis.net/docs/Extras.html).

Although I realize V2 was just released I am curious to know if anyone has had the opportunity to compare other opensource solutions such as gisgraphy.com.

I personally am interested in understanding the differences in terms of speed, features/options, accuracy, and the ease of being able to use ones own dataset(s).

Another geocoder to consider is Nominatim. It uses OpenStreetMap data.

For the usage policy of nominatim.openstreetmap.org, please see Nominatim usage policy. MapQuest also provide a version of this API, without the usage limits.

As for comparisons... I have not come across much in terms of benchmarks or a feature matrix to compare geocoding options. Though these links may help give you some addi
