I'm almost a novice with databases.
I created a PostgreSQL database with the python programming language.
I am pleased to note that the database was created as I wished. I could easily verify it from pgAdmin 4, the database administrator installed locally.
But now, since it is ready to be used, I would like to upload it to Heroku in order to work with it inside my web application.
I followed the various steps slavishly on the site of Heroku, but I can not complete the various steps, especially at the following command:
I wonder if it's an operating system problem, in the sense that the steps listed on the Heroku site could be os-agnostic and not addressed to Windows, the system I'm working on. I also believe that some commands are directed to connect the database that is located locally, not to migrate on the domain of Heroku.
