Review comment:
In a subsequent PR, I would like to suggest we consider making this
`Explain(ExplainNode)` or something, and having a separate `struct ExplainNode`
with these fields. There is a bunch of boiler plate code for matching and
reconstructing `LogicalPlanner` nodes that I think would be less awkward (and
require fewer changes to add / modify fields) if they were collected into a
struct
