Description
We previously print row-count statistics for
explain_query(..., physical=False), only. This PR updatesexplain_queryto print row-count statistics in more cases.The immediate goal here is to make it easier to understand how estimated row-counts relate the the physical plan.
In follow-up work, I'd like to add a feature to print the physical plan after execution (including real row-count statistics).
