intersect.sql query used by overlay command is out of date - the overlay query in create_designations_planarized is more efficient and does not rely on the additional ST_Safe* functions.
Note that the overlay command is not strictly necessary - we can overlay additional layers by adding them to the source list as designations. But that does get trickier to manage and a general overlay command is pretty useful.
