Yeah, I'd noticed that while reviewing the vacuum-multiple-tables patch.
My thought about fixing it was to pass a null RangeVar when handling a
table we'd identified through inheritance or pg_class-scanning, to
indicate that this wasn't a table named in the original command. This
only works conveniently if you decide that it's appropriate to silently
ignore relation_open failure on such table OIDs, but I think it is.
Not sure about whether we ought to try to fix that in v10. It's a
mostly-cosmetic problem in what ought to be an infrequent corner case,
so it might not be worth taking risks for post-RC1. OTOH, I would
not be surprised to get bug reports about it down the road.
