CLUSTER will eat maintenance_work_mem during index rebuilds --- more or

3.6Gb actually eaten, which is a bit sloppier accounting than I'd like
but not overly surprising. (FWIW, I think CVS HEAD is better than 8.0
at measuring sort workspace.)

Thanks for the clarification. It doesn't sound like it's going to jump to 8Gb and hog most of the RAM.
