I'm bringing this from another post, because I've narrowed down the problem
considerably, and it no longer corresponds neither to the headline nor to
the content of that post.
the following works fine, creating a valid connection:
connection = psycopg2.connect(database="test_db", user="test",
password="xxxxxx", host="xxxx-994.postgres.pythonanywhere-services.com",
port=10994)
the following fails:
db =
DAL("postgres://test:[email protected]:10994/test_db",
pool_size=configuration.get('db.pool_size'),
migrate_enabled=configuration.get('db.migrate'),
check_reserved=['all'])

psycopg2.OperationalError: FATAL: password authentication failed for user
"test"
The password is correct. It can't possibly fail. Besides the password
working in the db itself, t's the same very password that also works in
psycopg2.connect() call above.
How can I debug it further? What am I missing? What could be the reason?
I am getting exactly same problem (working for psycopg2.connect and not
working for DAL constructor with exactly same error) when 1) doing it from
web2py under PythonAnywhere and 2) web2py under my local windows PC (when
local, running the ssh tunnel, as prescribed elsewhere).
Please help!
