Demonstrate how to come up with a list of deltas between two data sets where either a spatial or attribute change has occurred. The PostGIS introduction covers the idea of evaluating spatial equality, but only adds an attribute about the match or not.
Combining attribute matching and geospatial matching to produce a delta table would be a good explainer of techniques.
