### Is your feature request related to a problem or challenge? Currently we cannot store `Arc<dyn PhysicalExpr>` inside `HashMap`. See [discussion](https://github.com/apache/arrow-datafusion/discussions/7906). Once we have this feature - [ ] Replace type `Vec<(Arc<dyn PhysicalExpr>, Arc<dyn PhysicalExpr>)>` with `HashMap<Arc<dyn PhysicalExpr>, Arc<dyn PhysicalExpr>>` - [ ] Reimplement `deduplicate_physical_exprs` algorithm so that it uses `HashSet`. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
