 * NOTES
 *	  An ACL array is simply an array of AclItems, representing the union
 *	  of the privileges represented by the individual items.  A zero-length
 *	  array represents "no privileges".  There are no assumptions about the
 *	  ordering of the items, but we do expect that there are no two entries
 *	  in the array with the same grantor and grantee.
 *
 *	  For backward-compatibility purposes we have to allow null ACL entries
 *	  in system catalogs.  A null ACL will be treated as meaning "default
 *	  protection" (i.e., whatever acldefault() returns).
