Somebody, somewhere has to programitacally handle the empty array. You are just suggesting that the database do it, not you.
Also, if you were selecting anything from an empty list and your program knows it is from an empty list, why even bother asking the database. The additional checks in your code can help reduce database calls and increase performance.

... but missing SQL for the empty list basically means that
we cant handle the empty set encoded in the empty array without
explicitly introducing code for this size of array. From a
programatically viewpoint, this seems quite odd.
