Original advisory details:

 Jingzhou Fu discovered that PostgreSQL incorrectly handled certain unknown
 arguments in aggregate function calls. A remote attacker could possibly use
 this issue to obtain sensitive information. (CVE-2023-5868)

 Pedro Gallegos discovered that PostgreSQL incorrectly handled modifying
 certain SQL array values. A remote attacker could use this issue to obtain
 sensitive information, or possibly execute arbitrary code. (CVE-2023-5869)

 Hemanth Sandrana and Mahendrakar Srinivasarao discovered that PostgreSQL
 allowed the pg_signal_backend role to signal certain superuser processes,
 contrary to expectations. (CVE-2023-5870)");
