Remarks

The ST_ConvexHull function returns the smallest convex geometry that contains all points of the input geometry. The convex hull is the geometric equivalent of stretching a rubber band around the outermost points of a shape. The result is always a convex polygon (or point/line for degenerate cases). This function is useful for simplifying complex geometries, finding bounding regions, or computational geometry algorithms. For a set of points, the convex hull forms the boundary of the minimal enclosing convex shape. OGC-compliant.
