23rd September 2021: PostgreSQL 14 RC 1 Released!


A vulnerability allows suppressing the normal checks that a SQL function returns the data type it's declared to do. These errors can easily be exploited to cause a backend crash, and in principle might be used to read database content that the user should not be able to access.
