Update to latest versions of PostgreSQL

2018-02-08 Security Update Release
==================================

The PostgreSQL Global Development Group has released an update to all supported
versions of our database system, including 10.2, 9.6.7, 9.5.11, 9.4.16, 9.3.21.
This release fixes two security issues. This release also fixes issues with
VACUUM, GIN indexes, and hash indexes that could lead to data corruption, as
well as fixes for using parallel queries and logical replication.

All users using the affected versions of PostgreSQL should update as soon as
possible. Please see the notes on "Updating" below for any post-update steps
that may be required.

Please note that PostgreSQL changed its versioning scheme with the release of
version 10.0, so updating to version 10.2 from 10.0 or 10.1 is considered a
minor update.

Security Issues
---------------

Two security vulnerabilities have been fixed by this release:

* CVE-2018-1052: Fix the processing of partition keys containing multiple
expressions
* CVE-2018-1053: Ensure that all temporary files made with "pg_upgrade" are
non-world-readable

Local fixes to the FreeBSD ports
--------------------------------

Inform users about data checksums [1].
Make sure /usr/bin/su is used regardless of PATH settings [2].
Enable DTRACE by default [3].
