[PATCH 09/14] perf script: Fix postgresql ubuntu install instructions

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Chris Phlipot <cphlipot0@gmail.com>

The current instructions for setting up an Ubuntu system for using the
export-to-postgresql.py script are incorrect.

The instructions in the script have been updated to work on newer
versions of ubuntu.

-Add missing dependencies to apt-get command:
    python-pyside.qtsql, libqt4-sql-psql
-Add '-s' option to createuser command to force the user to be a
    superuser since the command doesn't prompt as indicated in the
    current instructions.

Tested on: Ubuntu 14.04, Ubuntu 16.04(beta)
