Actually, I should have read your example more closely, I did not see
that you had set the type of the destination column to wkb.

This is not "recommended" behavior: wkb is not supposed to be a storage
type, just a type used in transition on the way out of the system.
However, in theory your commands should work, so we'll have a look, if
only to figure out why they failed. :)
