A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10,

to create non-temporary objects in at least one schema can execute arbitrary SQL
functions under the identity of a superuser. The highest threat from this
vulnerability is to data confidentiality and integrity as well as system
availability. (CVE-2020-25695)
