Comment(by strk):

 I meant the 3rd argument expected by the user callback signature. Does
 ST_MapAlgebra code checks that the 3rd argument expected by the user
 callback signature is of the "array" type ? To me, the less requirements
 we enforce, the better. Like if a user doesn't need custom arguments
 passed to the callback I would not even require a 3rd argument...

 In any case, for the sake of this ticket, anything that complains if a
 requirement is not met (rather than doing something which can be
 unexpected) is ok. Would be better to use other tickets for other
 enhancements (like changing the requirements).
