geo_cluster_within() GSERIALIZED ** geo_cluster_within ( const GSERIALIZED **  geoms, uint32_t  ngeoms, double  tolerance, int *  count  ) Return an array of GeometryCollections partitioning the input geometries into clusters in which each geometry is within the specified distance of at least one other geometry in the same cluster. Parameters [in] geoms Geometries [in] ngeoms Number of elements in the input array [in] tolerance Tolerance [out] count Number of elements in the output array Note PostGIS function: ST_ClusterWithin(PG_FUNCTION_ARGS)
