Security update for postgresql96 (moderate)

PostgreSQL was updated to 9.6.9 fixing bugs and security issues:

Release notes:

• <a href=“https://www.postgresql.org/about/news/1851/”>https://www.postgresql.org/about/news/1851/</a>

• <a href=“https://www.postgresql.org/docs/current/static/release-9-6-9.html”>https://www.postgresql.org/docs/current/static/release-9-6-9.html</a>

  A dump/restore is not required for those running 9.6.X. However, if you
  use the adminpack extension, you should update it as per the first
  changelog entry below. Also, if the function marking mistakes mentioned in
  the second and third changelog entries below affect you, you will want to
  take steps to correct your database catalogs.

Security issue fixed:

• CVE-2018-1115: Remove public execute privilege from contrib/adminpack’s
  pg_logfile_rotate() function pg_logfile_rotate() is a deprecated wrapper
  for the core function pg_rotate_logfile(). When that function was
  changed to rely on SQL privileges for access control rather than a
  hard-coded superuser check, pg_logfile_rotate() should have been updated
  as well, but the need for this was missed. Hence, if adminpack is
  installed, any user could request a logfile rotation, creating a minor
  security issue. After installing this update, administrators should
  update adminpack by performing ALTER EXTENSION adminpack UPDATE in each
  database in which adminpack is installed. (bsc#1091610)
