Hi, I have below queries: 1. How do i check the maintenance_work_mem for current session, before setting some other value for this parameter for the same session. 2. and How do I set maintenance_work_mem for a session only, and how will it be "rollback" once my maintainance work is done, Do I need to execute any command for that or just closing the session will rollback what I set for the session. Please respond me query wise. Regards, Atul
