I can't replicate that. I get either

ERROR: relation "foo" does not exist

if you specifically name a nonexistent table, or

WARNING: skipping vacuum of "foo" --- relation no longer exists

if the table existed at the start but doesn't exist by the time
vacuum gets to it. There may be some code path that results in
the error you cite, but you'll need to provide more detail about
how to duplicate it.
