I think the 7.4.x docs could do with a more explanation.
The 8.0 docs are better although a more explicit explanation stating that you MUST vacuum analyze template1 (periodically) would be useful.

However the implication (and my confusion) is that you need to vacuum your own databases only. It's not clear (to me) that you have to do the same for template0 and template1 as well.
You have to vacuum template1, but not template0 because the latter is marked not datallowconn. Not sure if this is adequately explained anywhere. The next-to-last para in section 21.1.3 does mention the datallowconn exception, but perhaps doesn't spell it out well enough.
