2.  How to upgrade PostgreSQL from 11 to 12
<https://www.kostolansky.sk/posts/upgrading-to-postgresql-12/>  . The steps
were written for Ubuntu / Debian, It should work the same by updating the
paths to correct Fedora related paths of PostreSQL installation.

Unfortunately, none of the tutorials describes the steps on how to port /
handle some manually created C extension functions libraries to the new
PostgreSQL instance.


Yes, the but guide for upgrading in the documentation does describe the step of porting extension libraries.  It says you need to do that before you run pg_upgrade and ensure that whatever is being installed onto the new server is binary compatible.  It even says explicitly that pg_upgrade cannot do this for you.
