Description

A simple repo:
When we typing

select -EXTRACT(DAY FROM birth_date) from cp.`employee.json`;

we probably mean

select -1 * EXTRACT(DAY FROM birth_date) from cp.`employee.json`;

However, the first one will trigger assertion error:
Error: SYSTEM ERROR: AssertionError: todo: implement syntax PREFIX(-(EXTRACT(FLAG(DAY), $0)))
