I know folks have talked about progress, but I haven't seen anything specific... could you add info about what table/index vacuum is working on, and how far along it is? I realize that's not very close to an actual % completion, but it's far better than what we have right now.

FWIW, the number I end up caring about isn't so much write traffic as read. Thanks to a good amount of battery-backed write cache (and possibly some iSCSI misconfiguration), our writes are generally much cheaper than our reads.
