Your installation references loadable libraries that are missing from the
new installation. You can add these libraries to the new installation,
or remove the functions using them from the old installation. A list of
problem libraries is in the file:
loadable_libraries.txt

[postgres@localhost ~]$ cat loadable_libraries.txt

Valid steps for upgrade from postgres 10 to 12 will be highly appreciated. As I didn't found any highly reviewed link that is complete. I am currently following with this link: https://www.postgresql.r2schools.com/how-to-upgrade-from-postgresql-11-to-12/. Replaced 10 for 11 in every command.

Thanks in Advance.
