Using Index to do sorting while using windowing function

Hi,

I was dealing with windowing function recently. I feel they are pretty
useful and quite handy in lot of operations.

I am not sure why but my PostgreSQL does not seem to be using indexes for
ORDER BY clause or PARTITION BY CLAUSE which I use with windowing function.
I have tried ORDER BY and GROUP BY clauses in a normal sql statement and
they seem to use indexes nicely.

Is this being already considered for development?
