It was difficult to review standalone, so I tried a quick version
myself and ended up with very similar results. The only substantial
difference was that I put back:

+ if (!vacuum_is_relation_owner(relid, classForm,
options))
+ continue;

in get_all_vacuum_rels() whereas your patch left it out -- double-check
that we're doing the right thing there.

Also remember to bump the catversion. Other than that, it looks good to
me.
