I haven't used PostGIS so I can't offer a real comparison. I think if you were to try out both, you'd be impressed with Solr's performance/scalability thanks in large part to its sharding. But for "functionality richness" in so far as geospatial is concerned, that's where Solr currently comes short. It just has the basic stuff 80% of people want.
