The following sections and chapters will also show you how these privileges are used. More detail about the meanings of these privileges appears below. The privileges applicable to a particular object vary depending on the object's type (table, function, etc.). There are different kinds of privileges: SELECT, INSERT, UPDATE, DELETE, TRUNCATE, REFERENCES, TRIGGER, CREATE, CONNECT, TEMPORARY, EXECUTE, USAGE, SET and ALTER SYSTEM. To allow other roles to use it, privileges must be granted. For most kinds of objects, the initial state is that only the owner (or a superuser) can do anything with the object. The owner is normally the role that executed the creation statement. Privileges can be inherited by roles using INHERIT to attribute automatically gain privileges of roles of which they are members.When an object is created, it is assigned an owner. On the other hand, just like any other privilege, you can pass down the right to own anything through the role members. This right cannot be given or withdrawn in and of itself. The permissions relevant to a particular object change based on the type of item, and the power to alter default privileges or destroy an entity is intrinsic to being the possessor of the object. Therefore to share or allow other roles access to the object it is necessary to grant privileges. The default state of a newly created object is that only the owner can interact with it. When an object (table, function, etc.) is created, an owner is immediately assigned, typically the role that executed the creation declaration is considered the owner. Roles can update or delete authority privileges on resources, in addition to establishing and revising other roles that govern who has authority over different entities.įurther, it is possible to offer participation as a role, making it possible for the individual role to use the privileges associated with the other position. Database objects (tables, functions, etc.) are owned by roles.
