How do I connect to Postgresql using SSL from SqlAchemy+pg8000?

Connecting to postgres via pg8000 from SqlAlchemy worked fine until I enabled SSL on postgres.

db = create_engine('postgresql+pg8000://user:pass@hostname/dbname', echo=True).connect()

Now it seems to fail with:

File "/Library/Python/2.7/site-packages/pg8000/core.py", line 872, in __init__
raise InterfaceError("communication error", exc_info()[1])
sqlalchemy.exc.InterfaceError: (InterfaceError) ('communication error', error(61, 'Connection refused')) None None

Answer

You need to add a connect_args dict:

db = create_engine(
    'postgresql+pg8000://user:pass@hostname/dbname',
    connect_args={'sslmode':'require'},
    echo=True,
).connect()
