   So the regression is that projection pushdown isn't working correctly.
   
   Maybe this is related to 
https://github.com/apache/arrow-datafusion/pull/8073 from @berkaysynnada ?
   
   Though it seems like the logical plan has the correct projection (of just 
`s`) pushed down. I am not sure why that projection gets lost in the physical 
plan
   
   ```
                   
"+---------------+--------------------------------------------------+",
                   "| plan_type     | plan                                      
       |",
                   
"+---------------+--------------------------------------------------+",
                   "| logical_plan  | Projection: (?table?.s)[x]                
       |",
                   "|               |   TableScan: ?table? projection=[s]       
       |",
   ```
