"This update for postgresql12 fixes the following issues :

Upgrade to version 12.7 :

CVE-2021-32027: Fixed integer overflows in array subscripting
calculations (bsc#1185924).

CVE-2021-32028: Fixed mishandling of junk columns in INSERT ... ON
CONFLICT ... UPDATE target lists (bsc#1185925).

CVE-2021-32029: Fixed possibly-incorrect computation of UPDATE ...
RETURNING 'pg_psql_temporary_savepoint' does not exist (bsc#1185926).

CVE-2021-3393: Fixed information leakage in constraint-violation error
messages (bsc#1182040).

Don't use %_stop_on_removal, because it was meant to be private and
got removed from openSUSE. %_restart_on_update is also private, but
still supported and needed for now (bsc#1183168).

Re-enable build of the llvmjit subpackage on SLE, but it will only be
delivered on PackageHub for now (bsc#1183118).

Disable icu for PostgreSQL 10 (and older) on TW (bsc#1179945).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
