-----------
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.
