I'm not sure what's best in terms of formatting details but I
definitely like the idea of making pg_waldump show more details. I'd
even like to have a way to extract the tuple data, when it's
operations on tuples and we have those tuples in the payload. That'd
be a lot more verbose than what you are doing here, though, and I'm
not saying you should go do it right now or anything like that.
