Update:
> * Allow the creation of indexes with mixed ascending/descending
> specifiers
>
> This is possible now by creating an operator class with reversed sort
> operators. One complexity is that NULLs would then appear at the start
> of the result set, and this might affect certain sort types, like
> merge join.
