You created a view that uses the catalogs and the structure of those catalogs has changed. pg_upgrade cannot fix this for you. Unfortunately, the only real solution is to have a pre-upgrade script that removes the not unusable view, perform the upgrade, and then run a post-upgrade script that replaces it with something that will work in the new system. I'm unaware of a version of PostgreSQL that would act as a transition version where both versions of the view could exist, but you may wish to double-check that if you think such a two-step upgrade path would be easier for you to manage.
