Nick, the issue would still remain if you set work_mem to 2Gb and joined 8 tables together, it would consume too much memory. So if you DO decide to proceed with this, I would recommend to err on the side of caution and be a little more concerned with tuning your SQL statements Good luck. ============================================= Romax Technology Limited A limited company registered in England and Wales.
