+ /**
+ * Separates a variant object/array into multiple rows, including nested
fields/elements when
+ * `recursive` is true. When false, the result schema is
+ * `struct<pos int, key string, value variant>`; when true, the result
schema is
+ * `struct<path string, pos int, key string, value variant>`.
+ *
+ * `pos` is the position within the parent, `key` is the object field name
or NULL for arrays,
+ * and `value` is the field/element value. In recursive mode, `path` is its
JSONPath. It ignores
+ * any input that is not a variant array/object, including SQL NULL, variant
null, and any other
+ * variant values.
