I think you must have, because the query output shows that sql_features,
its rowtype, and the information_schema all have OIDs much larger than
they would have had in a virgin installation. The large relfilenode
could have been explained by a VACUUM FULL, but the other OIDs wouldn't
have been changed by that.

That just means that information_schema is not in your search_path.
