Attribute dependency not captured for complex plans #671

We observed that when there are multiple nested queries along with window functions involved, attribute dependency not properly tracked. For example, avg_monthly_purhcase dependency should point to customer_id and purchase_amount but the link is completely broken. Attaching test queries and generated plan..

I will check if I can fix this when I get time. Able to reproduce and have a test query as well
