[postgis-users] Error when getting geometry as binary

[Paul Ramsey]

Well, I think it is still a valid bug, but you are trying to make WKB 
out of a bbox (the return from extent) and there is no such thing as a 
WKB bbox. So things should fail a little more gracefully. The 
envelope() trick turns the bbox into a polygon, for which there is a 
WKB form.
