The contents in the database are unchanged across the PostgreSQL restart; as such, there is no reason to invalidate the caches. This step was inherited from the general operating system upgrade documentation. When Python versions change, such as during OS upgrades, we must ensure that memcached is cleared. However, the `do-release-upgrade` process uninstalled and upgraded to a new memcached, as well as likely restarted the system; a separate step for OS upgrades to restart memcached is thus unnecessary.
