I don't think it's quite that easy when you consider user-defined
datatypes. Where are you going to get two sets of opclasses from?
Good point. I think if new index implementation does not change meaning
of strategy and function number old opclasses set could be used. And it
is only for new created or recreated indexes. Existing indexes will work
fine with old opclasses set.
