Access control requirements¶

Privilege	Object	Notes
OWNERSHIP	Snapshot	OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object, but can also be transferred using the GRANT OWNERSHIP command to a different role by the owning role (or any role with the MANAGE GRANTS privilege).

The USAGE privilege on the parent database and schema are required to perform operations on any object in a schema.
