**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** During optimization, we generate `filter` expressions that might benefit from being optimized to joins. Currently, where filters like these `where left_column = right_column` are converted to joins in the SQL planner (`plan_selection`). We should have a rule that does the same thing and let it replace the planner. **Describe the solution you'd like** Implement the where expression to join conversion in an optimization rule instead, so it can also be used after filters have been added to the plan. **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
