Remarks

The ST_Boundary function returns a geometry representing the boundary of the input spatial object according to the OGC SFS specification. For polygons, returns the rings (exterior and interior). For lines, returns the endpoints. For points, returns an empty geometry. The boundary is the set of points that form the closure of the geometry minus its interior. Useful for topological analysis, finding edges, or geometric computations. OGC-compliant.
