This is the quirks of OGC definition of contains and within. Contains and within only accounts the **interior** of larger object, obviously the **boundary** of a polygon is not contained by the **interior** of the polygon, so contains(poly, poly) should return false. PostGIS ST_Contains and ST_Within does not strictly implement the OGC contains/within semantics. There's a [ST_ContainsProperly](https://postgis.net/docs/manual-3.2/ST_ContainsProperly.html) for OGC-compliant semantics. -- This is an automated message from the Apache Git Service.
