There are two special types of users who implicitly get certain permissions — object owners and users with Superuser privilege. Ordinary users (other than these two types) must be granted specific permissions for them to be able to access the object in the desired manner.
Each object is associated with a user or group, which is referred to as its object owner. The object owner is special as far as the particular object is concerned and gets the following permissions on this object automatically:
1.
READpermission2. All extended permissions except
Extended Delete
Usually, the object owner is assigned higher permissions through the applied permission set. Permission sets are discussed later in this chapter.
