I'd expect 3,2,1 and 1.That's also a disingenuous example; what would you expect back from: select count_elements(string_to_array('butter,,milk',',')) I think the semantics you want is what you'd get from: array_filter_blanks(string_to_array($1,$2)) where I defined "array_filter_blanks" in my previous post.
I agree the function should not be changing values passed. Stripping/Dropping empty strings is changing what was passed into the function instead breaking it into a array.
