You didn't show us the rest of the command, but it looks like
this view contains a reference to pg_class.relhasoids.  As
Bruce noted, that column no longer exists, so you're not going
to be able to transparently upgrade this view.

I don't know what this view is from, though the schema name
"repack" is suggestive.  Possibly you could drop whatever it's
a part of, and then reinstall an updated version after upgrading?
