I would be appreciative of any > guidance offered. Unless that field is part of the key, I wouldn't think that a vacuum analyze would be needed, as the key distribution isn't changing. I don't know if that is still true if that field is indexed. Tom? Even then, as I understand things vacuum analyze doesn't rebuild indexes, so I could see a need to drop and rebuild indexes on a regular basis, even if you move that field into a separate table. -- Mike Nolan
