It's very desirable thing to be able to distinguish roles in consistent method 
of GiST: computation of distance could be very expensive and. The single way to 
provide it in current GiST interface is a strategy number. Of course, we could 
add 6-th argument to consistent to point role, but I don't think that's good 
decision.
