/*
 * All node's type of jsonpath expression
 *
 * These become part of the on-disk representation of the jsonpath type.
 * Therefore, to preserve pg_upgradability, the order must not be changed, and
 * new values must be added at the end.
 *
 * It is recommended that switch cases etc. in other parts of the code also
 * use this order, to maintain some consistency.
 */
typedef enum JsonPathItemType

some "switch" in the attached patch does not preserve the JsonPathItemType order
consistency, like executeItemOptUnwrapTarget.
