Really?  According to whom?  This works for me:

regression=# create schema "s'd"".s'd""";
CREATE SCHEMA
regression=# create table "s'd"".s'd"""."s's'd""." (f1 int);
CREATE TABLE
regression=# create sequence "s'd"".s'd"""."s's'd"".s" ;       
CREATE SEQUENCE
regression=# ALTER TABLE "s'd"".s'd"""."s's'd""." ADD COLUMN id bigint DEFAULT
nextval('"s''d"".s''d"""."s''s''d"".s"');    
 
ALTER TABLE

I think you've made up some theory about how to quote funny characters
in nextval's argument, and it's a wrong theory.  You have to double
single quotes because you're writing a string literal, but other than
that it should look just like a quoted identifier in SQL.
