I don't follow. xddouble can only expand to two quote marks, so how
does it matter which one we use as the result? This seems unlikely
to change the behavior. If it does, I think the real bug is elsewhere.
I do see a bug here --- I get
regression=# select """";
NOTICE: identifier """ [ lots o' rubouts ] @;" will be truncated to """"
ERROR: Attribute '""' not found
regression=#
