Reg - Autovacuum

[krishnaraj D <krishnarajd@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi All
                 I have installed a application with postgres-8.1.4 , I 
have to optimize the performance, As a measure i thought of enabling 
Auto commit , is it a right decision to take , If correct please suggest 
the steps that i need to follow in order to implement the Auto Vacuum.

                And also please suggest other steps that i need to 
improve the performance .

Thanks and Regards
Kris
