[postgis-users] ST_Equals with different geometry types

[Jose Carlos Martínez Llario]

Dear PostGIS list,
According to the OGC/SQL-MM in both standards this query should return 
true. JTS does.
I guess its because the geometry types are different but it shouldnt matter.
Its a bug or it is the expected behavior?
cheers,
Jose
