If you have an installation with many tables (100's to 1000's) or with some tables which autovacuum takes hours to process, you may want to add additional autovacuum workers so that multiple tables can be vacuumed at once. Be conservative, though, as each autovacuum worker will utilize a separate CPU core, memory and I/O.
