[sqlalchemy] Re: Connection error
Anyways guys I was able to fix the issue by installing a flask-specific version of the same package (even though I am not using flask) and I was able to get it to work just fine. Thanks everyone for your help.

[sqlalchemy] Re: Connection error
Yeah I connect to the DB over localhost:5432 via psql all the time and also haven't had any issues connecting via psycopg2. I also have no issue connecting to the database in sqlalchem, it's only an issue with sqlacodegen.

[sqlalchemy] Re: Connection error
Have you confirmed that you can connect to 127.0.0.1 at port 5432 using psql? On my development system, I normally use a local (UNIX domain) socket, which is libpq's default behavior. When I run "psql -h 127.0.0.1", I get the following error: psql: could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?
