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.
