For parallel query, we need to be able to pass a Plan to a worker, so that it knows what it's supposed to do. We could invent our own way of serializing plans for that purpose, but piggybacking on the existing node infrastructure seems like a much better idea. Initially, we'll probably only support a limited number of nodes within parallel workers, but this commit adds support for everything in plannodes.h except CustomScan, because doing it all at once seems easier than doing it piecemeal, and it makes testing this code easier, too. CustomScan is excluded because making that work requires a larger rework of that facility. Amit Kapila, reviewed and slightly revised by me.

|
* NOTES
|
|
* Path 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.
|
|
*
|
|
* Parse location fields are written out by outfuncs.c, but only for
|
|
* possible debugging use. When reading a location field, we discard
|
|
* the stored value and set the location field to -1 (ie, "unknown").
|
|
* This is because nodes coming from a stored rule should not be thought
|
|
* to have a known location in the current query's text.
