Update instructions

This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart PostgreSQL to make all the necessary changes.

Learn more about how to get the fixes.

The problem can be corrected by updating your system to the following package versions:

Ubuntu Release Package Version
17.10 artful postgresql-9.6 –  9.6.6-0ubuntu0.17.10
17.04 zesty postgresql-9.6 –  9.6.6-0ubuntu0.17.04
16.04 xenial postgresql-9.5 –  9.5.10-0ubuntu0.16.04
14.04 trusty postgresql-9.3 –  9.3.20-0ubuntu0.14.04
