   > Why we need this func (e.g.,. other systems support this func)? Seems like the example abolve is the same with `array_contains(array(1, 2, 3), 2)`.
   
   If  we need to judge  `SELECT _FUNC_(array(1, 2, 3), array(2, 3))` ? 
   PostgresSQL support this  and in  our job logical need this func,  I will  check other engine.
