What I take away is you can do it either way as long as you’re bought in and are familiar with the process. For me it’s no trouble at all to define my schema in advanced. And Postgres provides me with the json column escape hatch. Combined with the massive benefit of the data validity guarantees later in the app’s lifecycle I pick Postgres every time.
