This release requires "postfix stop" before updating, or before

rest of Postfix, causing mail delivery delays until Postfix is
restarted.
This seems to be contradicting itself. Do we have to stop postfix
before updating, or do we have to restart postfix after updating?
Restarting postfix is much faster than than stopping it, installing
the update, and then starting, so I wold prefer to restart if will
work.
Perhaps you are confused because of your distributor's abstraction of
postfix(1) commands? There is no "postfix restart" command. There is
[among others] reload, start, and stop. You need to do whatever
translates to "postfix stop" and then "postfix start". (And yes, use
"postfix start-fg" if that's what your OS requires.)
