error installing psycopg2

	-(option1) Incase you encounter an error installing psycopg2,
      try installing the binaries instead:
pip install psycopg2-binary

	-or (option2) downgrade the header file libpq5
sudo aptitude install libpq-dev   # aptitude is recommended since it is better when it comes to resolving dependencies

accept the solution that recommends downgrading libpq5(usually the second recommended action)

pip install psycopg2
sudo apt-get install -y libpq5      # undo the downgrade
