+ The right to drop an object, or to alter its definition in any way, is
+ not treated as a grantable privilege; it is inherent in the owner,
+ and cannot be granted or revoked. (However, a similar effect can be
+ obtained by granting or revoking membership in the role that owns
+ the object; see below.) The owner implicitly has all grant
options for the object, too.
