Jeff Davis ff9618e82a Fix MAINTAIN privileges for toast tables and partitions.
Commit 60684dd8 left loose ends when it came to maintaining toast
tables or partitions.

For toast tables, simply skip the privilege check if the toast table
is an indirect target of the maintenance command, because the main
table privileges have already been checked.

For partitions, allow the maintenance command if the user has the
MAINTAIN privilege on the partition or any parent.

Also make CLUSTER emit "skipping" messages when the user doesn't have
privileges, similar to VACUUM.
