Unable to upgrade to postgresql 13

I'm getting the following error: > postgres@:~/>cat loadable_libraries.txt could not load library >"$libdir/plpython2": ERROR: could not access file >"$libdir/plpython2": No such file or directory In database: db_name When trying to run pg_upgrade from PostgreSQL-11 to PostgreSQL-13. /usr/pgsql-13/bin/pg_upgrade -b /usr/pgsql-11/bin -B /usr/pgsql-13/bin -c -d /localpart0/db/postgres/11/db_name/data -D/localpart0/db/postgres/13/db_name/data -j 20 -r -v --clone I don't have any plpython* extensions and already tried changing the pg_pltemplate entries for plpythonu and plpython2u to plpython3 and run the pg_upgrade but it fails either way. Installed Packages: > postgresql11-plpython.x86_64 11.7-1PGDG.rhel7 @postgres11.prd > postgresql13-plpython3.x86_64 13.1-1PGDG.rhel7 @postgres13.prd Any guidance would be greatly appreciated.
