Hi Pedro,

take only the outer Polygon (ST_Boundary) from your query or simpler the 
centroid from extent.

Hi all,

I'm trying to get the centroid of a list of points and I'm a bit unsure on how 
to proceed. The first thing that came to mind was converting the list of points 
to a polygon but that wouldn't always return a "clean" polygon (e.g. inner 
points) ... Any thoughts would be greatly appreciated :)

BR,
