Description Michael Kaplan 2021-02-02 12:16:06 UTC 
A user having some UPDATE privilege on a partitioned table but lacking the
SELECT privilege on some column may nonetheless be able to acquire
denied-column values from an error message.  This is similar to CVE-2014-8161,
but the conditions for exploitation are more rare.

The PostgreSQL project thanks Heikki Linnakangas for reporting this problem.
