What do you mean by ‘idle’?

If you mean your database is seeing extended periods of no updates to a table, you still want to vacuum, maybe even vacuum full if you know when traffic stopped and for how long to get the best possible read performance.

If you have quiet periods in both reads and writes, enjoy the luxury of having an unused database to operate.
