HELP WITH 'Data Exchange Service' POSTGRESQL

If you have suggestions for the course I’d suggest adding them to this section of the forums Suggestions; Feature and Course Requests - Codecademy Forums, make sure to keep the URL and any useful info.

If you’re looking for assistance from other users it would help you if you break any questions down into something others can answer, How to ask good questions (and get good answers) has some good advice on this front.
