Changes between Initial Version and Version 1 of Ticket #45299, comment 3

initial	v1
2	2
3	3	- [attachment:"45299-bug1.diff"] matches the check used next block down for `ARRAY_*`.
4		- [attachment:"45299.diff"] `get_col()` differs from the rest of the `get_*()` methods ~~which return `null` in this case,~~ and always returns an array, so this also seems like a sane change.
