But (unless you are on a really old version of PG) you really shouldn't need to manually vacuum things as that is the job of the autovacuum process. There are unusual situations that suggest a manual analyze. It should be run right after a cluster for instance. But they are limited special cases. What indicates that you need to vacuum or analyze via cron?
