> For example:
> Query SQL is
> {code:java}
> select a, sum(b) from table group by a order by 2{code}
> When we convert this sql to relNode and convert it back to SQL by
> RelToConverter, the result is:
> {code:java}
> select a, sum(b) from table group by a order by sum(b){code}
> But we want to keep order by column to ordinal.
> Would we add a switch in RelToConverter to control whether convert sort by
> column to expression or ordinal?
> Maybe we can use method isSortByOrdinal in dialect SqlConformance?
