The concept of startup_tuples for a WindowAgg looks good to me, but I
can't follow up with the below line:
+ return clamp_row_est(partition_tuples * DEFAULT_INEQ_SEL);
# select count(*) over() from tenk1 limit 1;
count

10000 --> We need to scan all the tuples.
Should we just return clamp_row_est(partition_tuples)?
