A flaw was found in postgresql. A purpose-crafted query can read arbitrary
bytes of server memory. In the default configuration, any authenticated
database user can complete this attack at will. The attack does not require
the ability to create objects. If server settings include
max_worker_processes=0, the known versions of this attack are infeasible.
However, undiscovered variants of the attack may be independent of that
setting.
