Public bug reported:

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)

    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:
