      Autopilot test case: features.windowFunctions

      There seems to be an issue with window functions and it is affective all window functions. The issue with the query selects from a subquery, it returns only one row, instead of N rows in the table. The query in question is in the following general syntax pattern:

      select o_custkey, corr(o_custkey,o_orderkey) OVER (PARTITION BY 55 ) from (select * from orders where o_custkey <= 20000) s order by 1, 2;

      The following syntax pattern seems to be ok

      select o_custkey, corr(o_custkey,o_orderkey) OVER (PARTITION BY abs(o_custkey)+2 ORDER BY o_custkey ,o_orderkey ,o_orderdate ROWS BETWEEN 15 FOLLOWING AND 15 FOLLOWING) from orders order by 1, 2;

      Here is a window function test result summary comparison:
