      Description

      RelToSqlConverter does not currently support sub-queries (RexSubQuery), but it should.

      SqlToRelConverter, in the default configuration, converts sub-queries into Join clause. But when SqlToRelConverter.Config.expand = false, it does not convert them to Join. And that causes problems because RelToSqlConverter cannot handle them.
