An object owner is the user who creates a particular database object and can perform any operation on that object.
An object owner is the user who creates a particular database object and can perform any operation on that object. By default, only an owner (or a superuser) can act on a database object. In order to allow other users to use an object, the owner or superuser must grant privileges to those users using one of the GRANT statements.
Note
Object owners are PUBLIC users for objects that other users own.See Database privileges for more information.
