Should I temporarily increase sort_mem, vacuum_mem, neither, or both when doing a CLUSTER on a large (100 million row) table where as many as half of the tuples are deadwood from UPDATEs or DELETEs? I have large batch (10 million row) inserts, updates, and deletes so I'm not sure frequent vacuuming would help.
