Not using that particular syntax, but you can do that if you create the
appropiate operator classes. Note that if you want to use btree index
on a single column, you don't need to have a descending index, because
btree indexes can be scanned in either direction. The opclass trick is
only needed if you want to have a multicolumn index. (I guess in the
other access methods it doesn't make much sense to think of descending
indexes.)
