Review comment:
Hi, @francis0407 . I have some questions beyond of the current
implementation of this PR. Currently, this PR aims to add `ANY/SOME` over a
query.
1. Are we going to extend this to 'ALL' later? e.g. `SELECT 1 > ALL (SELECT
0)` (PostgreSQL example)
2. Are we going to support `array`, too? e.g. `SELECT 1 > ANY (ARRAY[0,1])`
(PostgreSQL example)
