[GitHub] [arrow-datafusion] andygrove opened a new issue, #2164: Introduce AliasedRelation in logical plan

andygrove opened a new issue, #2164:
URL: https://github.com/apache/arrow-datafusion/issues/2164

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   If I have a SQL query such as `SELECT * FROM person AS peeps` there is no way to extract the original table name `person` from the logical plan. It looks like the alias name is pushed down to the `TableScan` node and the original name is discarded.
   
   **Describe the solution you'd like**
   
   I would like to include an `AliasedRelation` node to better represent the query. 
   
   For example:
   
   ```
   Projection(*)
     AliasedRelation(name="peeps")
       TableScan(name="person")
   ```
   
   This would not change the physical plan.
   
   **Describe alternatives you've considered**
   None
   
   **Additional context**
   None
