Comment(by pramsey):

 This is a lot less obvious that something like ST_Buffer, because
 translate is very sensitive to what the cartesian system actually is. A
 translate that ends up round-tripping into polar stereographic, for
 example, could provide very surprising results to people!

 A more deterministic variation would be to make ST_Project accept geometry
 types other than point. The whole object would be moved the desired
 distance and direction, which is what people translating generally want,
 no?
