[postgis-users] ST_ConvexHull with millions of records...

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
