Yes what the code does is very clear, but the function call is even a level up clearer, maybe you don't want to know how it does it's job, you just want an array of values in a column (array_column(array, column)). Personally I like comprehensions, but I tend to disguise them behind a function, it's much more clear to me. (but if I need the code to be super fast, I avoid using an extra function.)
