I was wondering if the documentation on SupportsReportStatistics  about its interaction with the planner and predicate pushdowns is still accurate. It says:
"Implementations that return more accurate statistics based on pushed operators will not improve query performance until the planner can push operators before getting stats."
Is this still accurate? When looking through the code it seems like there is now functionality that explicitly wants the operators pushed down . Is the documentation for SupportsReportStatistics referring to something other than  or should it be updated?
