An information leak was discovered in postgresql in versions before 13.2,
before 12.6 and before 11.11. A user having UPDATE permission but not
SELECT permission to a particular column could craft queries which, under
some circumstances, might disclose values from that column in error
messages. An attacker could use this flaw to obtain information stored in a
column they are allowed to write but not read.
