Security update for postgresql12 (moderate)

An update that solves three vulnerabilities and has three
fixes is now available.

Description:

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 outputs for joined cross-partition updates (bsc#1185926).

• 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).
