ST_ConcaveHull Returns the 'concave' hull of the input geometry, containing all of the source input's points, and which can be used to cr...eate polygons from points. The ratio parameter dictates the level of concavity; 1.0 returns the convex hull; and 0 indicates to return the most concave hull possible.
