Message-ID: <CABeG9LtsAVP4waKngUYo-HAiiowcb8xEjQvDDfhX_nFi5SJ4jw@mail.gmail.com> (raw)

Hi,

Today looking for information on hard limits for
autovacuum_vacuum_cost_limit I found myself with a very short
description in the docs.

This is a patch to add some further description, plus the upper and
lower limits it has.
