Sqlalchemy.exc.operationalerror: (psycopg2.operationalerror)

My Flask app(postgresql db) is working fine in local. I pushed my code to server and there I tried to run.py db migrate, it throws me these errors Traceback (most recent call last)

Solution 1:

Fixed it with a `sudo.

sudo run.py db migrate

I know it is weird but yes, sudo did the trick
