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=#
