stringToNode() for plan nodes...
Hi!
I have a problem with stringToNode() function. I'm trying to convert a
Plan into its ASCII representation. This seems to succeed. The problem
is that when I try to convert it back with stringToNode() the following
error is reported:
" ERROR: badly formatted node string "SEQSCAN :startup_cost 0.00
:tota"... "
In other words stringToNode(nodeToString(plan)) fails.
I've read somewhere that there is no support in stringToNode() for Plan
nodes.Is this true? I want it to work in order to store (in ASCII
format) and then read a Plan from disc. Any suggestions...?
Thanks in advance!

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.
