Thanks for the review. I've found another crash today and attached is
fixed version. The case is:

SELECT four, sum(ten) over (PARTITION BY four ORDER BY four RANGE 1
PRECEDING) FROM tenk1 WHERE unique1 < 10;

The planner recognizes windowagg->ordNumCol as 0 for optimization, but
RANGE offset cases should really have interest on that value as the
syntax says.
