PostGIS is a fantastic, battle-tested suite of GIS extensions for Postgres. It handles most aspects of it, and is widely used, for example in OpenStreetMap’s Mapnik. But for your project, it’s most likely overkill. In a Q and A fashion, let’s discuss reasons for (not) using it.I need to store geographical data together with my entities. Google and StackOverflow tell me that I need PostGIS’s Geometry objects.You’ll likely be using a very large cannon to shoot a tiny bird. Geometry is a flexible type that can store a point, a collection of points, a shape or a collection of these.
