So it's better to check for == 0? What's the difference? Is an IS_NULL check slower?

No, it's not slower, but it makes no sense to compare variable value to a type constant. Even if coincidentally constant value is the same one you need to compare to.

OK, so if I clean up those patches and re-send, will one of them be applied?

(It'd be nice to have some idea which one...)
