13  * NOTES
14  * Path nodes do not have any readfuncs support, because we never
15  * have occasion to read them in. (There was once code here that
16  * claimed to read them, but it was broken as well as unused.) We
17  * never read executor state trees, either.
18  *
19  * Parse location fields are written out by outfuncs.c, but only for
20  * possible debugging use. When reading a location field, we discard
21  * the stored value and set the location field to -1 (ie, "unknown").
22  * This is because nodes coming from a stored rule should not be thought
23  * to have a known location in the current query's text.
