The PostgreSQL project reports:

Memory disclosure in INSERT … ON CONFLICT … DO UPDATE

    Using an INSERT ... ON CONFLICT ... DO UPDATE command on a
    purpose-crafted 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 cannot use
    this attack at will..
  



    Buffer overrun from integer overflow in array subscripting
    calculations
  

    While modifying certain SQL array values, missing bounds checks let
    authenticated database users write arbitrary bytes to a wide area of
    server memory.
