Thanks @jemrobinson, cc'ing additional developers for review/comment. A couple of comments:

• looks like there are some flake8 errors
• can we add to the PostgreSQL provider tests? Suggest creating another config fixture with properties set and run tests to confirm it works

@tomkralidis thanks for pointing those out. I've fixed the flake8 errors and added a test. Let me know if you'd like me to make any other changes.

Thanks @jemrobinson ; looks like there are some flake8 failures in tests/test_postgresql_provider.py

Sorry! Should be fixed now.

Thanks @jemrobinson !
