Thanks for giving it a readthrough! Just wanted to mention that even though I'm critical about this one thing, your article as a whole is superb. If people start their Go projects using pgx, tern, and have tests for their database functionality, they're going to be set up for a lot of success. The interface thing is just a minor annoyance I have because I see so many people doing it. (I'm sure my past self has done it more times than I'd like to admit.)
