The result after 0001 is applied is that a couple of
object_ownercheck() calls that existed before ff9618e are removed from
some ACL checks in the REINDEX, CLUSTER and VACUUM paths.  Is that OK
for shared relations and shouldn't cluster_is_permitted_for_relation()
include that?  vacuum_is_permitted_for_relation() is consistent on
this side.

Here are the paths that now differ:
cluster_rel
get_tables_to_cluster
get_tables_to_cluster_partitioned
RangeVarCallbackForReindexIndex
ReindexMultipleTables

0002 looks OK to retain the skip check for toast relations in the
VACUUM case.
