The main factor here is resource utilization: a lot of companies have enough data that would need days to be vacuumed concurrently. Is the implementation discussed there pausable or at least cancellable? Does it take into account periods of high resource utilization by user-generated queries?

If you want to discuss the patch on the other thread, you should go
read that thread and perhaps reply there, rather than replying to this
message. It's important to keep all of the discussion of a certain
patch together, which doesn't happen if you reply like this.

Also, you've already been asked not to top-post and you just did it
again, so I'm guessing that you don't know what is meant by the term.
So please read this:

If you're going to post to this mailing list, it is important to
understand the conventions and expectations that people have here. If
you insist on doing things differently than what everyone else does,
you're going to annoy a lot of people.
