Good afternoon, The PostgreSQL 10.4 upgrade involves changes to some function markings (see release notes, E.1.2, second and third bullet points for specifics). One way to make these changes is to use `ALTER FUNCTION` to change the functions in your existing databases. While this was mainly straightforward, I'm unclear on whether the `template0` database must be changed in this manner or if it is automatically updated when the upgrade is applied. The documentation indicates that in general you shouldn't manually change the `template0` database.
