It might be a convenient feature to encourage exploration if, like the Hasura.io setup, Observable will help you generate and authenticate to a blank Heroku Hobby Postgres database using OAuth:
The Heroku app repository it creates is completely blank, it seems to just run the postgres plugin creation. The plugin may not even go to sleep, not sure.
Great idea! Would you mind suggesting this as a feature request in our feedback repo? If you log it there, you will get notified of progress and any further discussions about that feature request…
If you would rather I log it on your behalf, let me know (but then you won’t be on the notification list of that issue…)
