Hmm, I wasn't aware that Ubuntu's (?) default unattended-upgrades config makes it upgrade Ubuntu packages only.
By default it only upgrades from an approved list of sources. One could include PGDG repos in that list if you desired.

You can install a /usr/sbin/policy-rc.d file [1]. That will allow filtering the start/stop actions issued by package activity.

Restarting after install is actually the default since a while ago. (Previously packages were doing stop-upgrade-start.)
Right but I mean restarting like later in the day or week. Not immediately after the upgrade when we aren't ready for it.
