> For an indexnl plan, we currrently do not show card/cost in the explain output. These annotations are added at the end of join enumeration on the logical operators in EnumerateJoinsRule. For indexnl join, there are no corresponding physical operators (as the data scan gets converted into unnest_map), so these cards are not accessible in the final EstimatedCostComputationVisitor code.
