commit 5389e3d7886af68cdae3ea17824ef394055fd915 Author: Hari krishna <[email protected]> AuthorDate: Fri Dec 1 12:29:46 2023 +0530 Fix query fallback when subqury present within LEAST()/GREATEST() (#16777) * Fix query fallback when Subqury present within LEAST()/GREATEST() Currently, Query fallsback to the planner when a subquery is present in a ScalarMinMax (LEAST, or GREATEST) expression. In This PR, I am addressing the situation by incorporating the ScalarMinMax operator when processing scalar operators with subqueries. support subquery within ScalarArrayRef/ScalarArrayRefINdexList
