No, there isn't any particular reason that index extensions should be
considered database-wide resources; if operators are named local to
schemas, then opclasses can be too, and that's all you need.
In practice maybe it doesn't matter; I doubt anyone would try to
implement an indexable datatype in anything but C, and to define
C functions you must be superuser anyway. But this does not seem
to me to be a good argument why operator names should be global.
