33: Postgres PubSub and Elixir with Allen Wyma

We talk with Allen Wyma about a Postgres PubSub feature and how it plays nice with Elixir. We dispel the idea that you should always use Phoenix PubSub just because it's there and we cover the value of learning what's built-in to tools like the postgrex library. Allen shares how Postgres PubSub elegantly solved a problem for him and he gives tips for using it. We also talk about teaching Elixir through Allen's YouTube videos and teaching in person with his Teach Me Code efforts.
