Review Comment:
I believe we need a new stage because this must be done after analysis but
before we normalize the plan for cache lookup. It would be great to use
`FinishAnalysis` in the optimizer but I feel like it is too late.
I also worry about just doing this refresh all the time. We may remember the
analysis finish time and only refresh if it is older than 100ms or so to not
refresh unnecessary.
Thoughts?
