Hmm, I couldn't understand the benefit of this patch. Would you
elaborate it a little more?

Multiple autovacuum worker can work on one database. So even if a
table that you want to vacuum first is the back of the list and there
other worker would pick up it. If the vacuuming the table gets delayed
due to some big tables are in front of that table I think you can deal
with it by increasing the number of autovacuum workers.
