pip install -r requirements.txt fails on mac due to psycopg2

Hi, nice project! However, out of the box, users may find compatibility issues due to psycopg2, which is notoriously a bit finnicky. Initially, when I tried to pip install psycopg2, I got some errors like

  pg_config is required to build psycopg2 from source.  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'.

  If you prefer to avoid building psycopg2 from source, please install the PyPI
  'psycopg2-binary' package instead.

However, I had no issue with psycopg2-binary. You may want to make a note of it in the readme and/or make psycopg2-binary the default. You may mention this in the videos - I admit I haven't watched them yet! But I know a lot of folks just like to jump straight into the codebase.

I had an issue with psycopg2-binary for a long time while on windows. You might need to make sure your computer has a c++ compiler installed.
