   Not sure if this can be a generic method on `LogicalPlan` itself, as for example if you join two tables with different catalog names, then what would the `catalog_name()` method return for a `Join` logical plan node?
   
   Currently you can kinda retrieve the catalog name from a `TableScan` logical plan node via its `table_name` field.
   
   Could you expand on the potential use case for such a method to give some more context?
