Title:
  Add libpg-dev to developer docs

Status in OpenStack Identity (keystone):
  Fix Released

Bug description:
  When setting up a development environment following the instructions
  here:

  http://docs.openstack.org/developer/keystone/devref/development.environment.html

  On Ubuntu 16.04.1 when installing dependencies from test-
  requirements.txt using pip, the installation fails when it tries to
  install psycopg2:

  Collecting psycopg2>=2.5; extra == "postgresql" (from oslo.db[fixtures,mysql,postgresql]>=4.1.0->-r test-requirements.txt (line 13))
    Downloading psycopg2-2.6.2.tar.gz (376kB)
      100% |████████████████████████████████| 378kB 769kB/s
      Complete output from command python setup.py egg_info:
      running egg_info
      creating pip-egg-info/psycopg2.egg-info
      writing pip-egg-info/psycopg2.egg-info/PKG-INFO
      writing top-level names to pip-egg-info/psycopg2.egg-info/top_level.txt
      writing dependency_links to pip-egg-info/psycopg2.egg-info/dependency_links.txt
      writing manifest file 'pip-egg-info/psycopg2.egg-info/SOURCES.txt'
      warning: manifest_maker: standard file '-c' not found

      Error: pg_config executable not found.

      Please add the directory containing pg_config to the PATH
      or specify the full executable path with the option:

          python setup.py build_ext --pg-config /path/to/pg_config build
  ...

      or with the pg_config option in 'setup.cfg'.

      ----------------------------------------
  Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-j460mO/psycopg2/

  
  Googling this error brings you to this fix from stackoverflow:

  http://stackoverflow.com/questions/11618898/pg-config-executable-not-
  found

  Which simply involves installing the libpq-dev package.  This fixes
  the problem and the rest of test-requirements.txt are installed fine.

  Recommend adding libpg-dev (Ubuntu/Debian) along with other package
  managers to the list of dependencies to install before using pip:
