    Description

      JDBC adapter incorrectly pushes windowed aggregates down to HSQLDB. Queries containing window functions fail when using HSQLDB (or any other DB that does not support window functions) because the optimizer converts them to native SQL with window functions which are not supported by HSQLDB. For example:

      select "store_id", "product_id", sum("unit_sales") unit_sales, row_number() over (
      partition by "store_id" order by sum("unit_sales") desc
      ) row_num
      from "sales_fact_1998"
      group by "store_id", "product_id"
