Why would you doubt the statement in readfuncs.c?
* NOTES
* Path and Plan nodes do not have any readfuncs support, because we
* never have occasion to read them in. (There was once code here that
* claimed to read them, but it was broken as well as unused.) We
* never read executor state trees, either.
