I've not read a word spoken against the general idea, so I think we
should pursue this actively for 8.3. It should be straightforward to
harvest the good ideas, though there will definitely be many.

Perhaps we should focus on the issues that might result, so that we
address those before we spend time on the details of the user interface.
Can we deadlock or hang from running multiple autovacuums?
