[pgadmin-hackers] 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?

Re: [pgadmin-hackers] [HACKERS] Changes in Trigger Firing
One scenario where I can forsee an issue is when someone uses the tablename with-in the trigger function on which the trigger was fired. I am not sure how and what issue might crop up but this will be one of my test cases.
