I took another look at v32-0001 and v32-0002, and they look reasonable to me. Unless additional feedback materializes, I'll plan on committing those soon.
After that, it might be a good idea to take up the vacuumdb changes next, since there's been quite a bit of recent discussion about those. I have a fair amount of experience working on vacuumdb, so I could probably help there, too. -- nathan
