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? regards, tom lane
