It is not possible to access Postgres based CloudSQL from Python on AppEngine standard. See here:

https://cloud.google.com/sql/docs/postgres/connect-app-engin...

Note that only node and Java are listed under non-Flex.

I got burned by this and had to start over with MySQL.

It is possible on the new (beta) Python 3. 7 runtime on AppEngine standard:

If you're an existing AppEngine standard user/customer, it's pretty likely that that means you will not be able to take advantage of PostgreSQL, as the new runtime does NOT give you access to a ton of their existing services that you are probably already using (such as datastore.)

Then they should update their docs.
