Unfortunately I don't see a way for that. GIN is generalized - and it doesn't 
know semantic. Actually, we could fix first five strategy numbers for BTree's 
strategies, and then we could teach GIN core to use BTRee semantic, but what 
about with already existed operator classes?

Anyway GIN couldn't be used for ORDER BY clause.
