* Geometry dicing for speedier performance in data grouping and proximity analysis,
* Geometry clustering

Geography - Proximity analysis using KNN (new in PostGIS 2.2)
Raster - in-database raster coverage making
Topology - geometry simplification that maintains connectedness of adjoining geometries
Geocoding and Address Standardization - Basic examples using PostGIS Tiger Geocoder, and address standardizer (new in PostGIS 2.2.)
