Remove "stop words" from Postgres full text search

I have a Django app deployed on Heroku. In the app, I have a specific view that returns full text search, and I need stop words (“I, the, above, under”, etc) to be included. I found a link (see below) that indicates how remove the stop words using raw SQL commands, but I have no experience doing this type of thing and I’m wondering if anybody can give me some insight as to how to implement this in the code of my Django project.

What the code in that link refers to are steps that you can take when preparing the database, not something you would necessary do in your queries. There’s nothing that you would need to do within your Django project.
