I use Fedora OS and I've a set up and running PostgreSQL10 instance that
I've installed using
*dnf install postgresql10**. Sicne I've decided to upgrade directly to 12
instead of to 11 I've installed the 12 version using *dnf install
postgresql12**. I'm currently following the steps described in:

1. UPGRADE POSTGRESQL 10 To 11
<https://dbtut.com/index.php/2018/10/30/upgrade-postgresql-10-to-11/> . It
has some syntax errors in the suggested command lines that I've corrected on
my side.

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.
