Hi, The ST_ConvexHull function generates exactly the geometry that I need to get the area covered by each of my tables. By cons, some of them have millions of records and the operation crash.
Is there a way to generate a geometry using the function ST_ConvexHull but by reducing the precision or by a process of aggregation? The accuracy is not required in my case, only to get an idea of the scope of data foreach table. regards, MartinO
