This is the existing behavior on HEAD. I think it has been this way for a
while. Granted, that doesn't mean it's ideal, but AFAICT it's intentional.
Looking closer, the database ownership check in
get_tables_to_cluster_partitioned() appears to have no meaningful effect.
In this code path, cluster_rel() will always be called with CLUOPT_RECHECK,
and that function only checks for table ownership. Anything gathered in
get_tables_to_cluster_partitioned() that the user doesn't own will be
skipped. So, I don't think my patch changes the behavior in any meaningful
way, but I still think it's worthwhile to make the checks consistent.
