Update instructions

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

Ubuntu 19.04

• postgresql-11 - 11.3-0ubuntu0.19.04.1

Ubuntu 18.10

• postgresql-10 - 10.8-0ubuntu0.18.10.1

Ubuntu 18.04

• postgresql-10 - 10.8-0ubuntu0.18.04.1

Ubuntu 16.04

• postgresql-9.5 - 9.5.17-0ubuntu0.16.04.1

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.
