I am trying to connect my Google Colab to my Postgres DB. When I try to connect to from Jupyter Notebook it's working, so I'm guessing that my credentials are fine. This is the error that I got:

> 
> could not connect to server: No such file or directory
> 
> 
> Is the server running locally and accepting
> connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
>

How can I solve it? My Postgres running on my machine.

Thanks!
