- blackflame7000 7y agoYea PostGIS is a must if you plan on doing any sort of geospatial work with Postgres. PostGIS is way ahead of most other databases when it comes to processing geographic (3D) types. For example calculating a 100km buffer zone for 2D geometry types is easy, but only PostGIS can support buffer zone calculations on 3D geographic types. Because of the curvatures of the earth, the math is quite involved but it can make a big difference in accuracy
