Change database url from postgres: to postgresql: This is needed to give us a working mailman even with the latest updates installed. This is copy&paste from stackoverflow, which says on https://stackoverflow.com/questions/62688256/sqlalchemy-exc-nosuchmoduleerror-cant-load-plugin-sqlalchemy-dialectspostgre The URI should start with postgresql:// instead of postgres://. SQLAlchemy used to accept both, but has removed support for the postgres name.
