Обсуждение: 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?
