Yeah, Tom, I think you are on to something. I couldn't figure out where
the r.relhasoids was referenced in the rest of the log output, but if it
is on the lines that are part of CREATE VIEW, it certainly could be the
case that the view references a pre-PG-12 column of pg_class. To fix
it, Tom is right that removing the view then recreating it with PG-12
pg_class column assumptions is the right fix. I actually rarely see
this kind of failure.
