   Thanks for the proposal.
   
   imo it is a bit counter-intuitive to write `SELECT MIN(c1) FROM table1` and get `MIN(table.c1)` as the schema. Are there other engine doing this?
   
   I am curious how this interacts with the dataframe API. E.g. (pseudo-code)
   
   ```rust
   df = ctx.create_in_memory_table("table1", batches)?;
   df = df.agg(sum(df["c1"]))?;
   df.collect()
   ```
   
   would yield the schema `"SUM(table1.c1)"` or `"SUM(c1)"`? Would I need to write `df = df.agg(sum(df["table.c1"]))?;` instead?
