Description
The PostgreSQL project reports: Using an UPDATE ... RETURNING on a purpose-crafted partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will. A user lacking the CREATE and TEMPORARY privileges on all databases and the CREATE privilege on all schemas typically cannot use this attack at will.
