Box distance operators not available with PostgreSQL 9.0

The ←> and <#> operators are not available when building against PostgreSQL 9.0, but there's really no reason for that IMHO.
Beside, docs do not say anything about that.
I think operators should exist. Only, the KNN index would not be available for PostgreSQL < 9.1.
