Could that be also the cause for the two bugs that I have been reported
some time ago occuring when object names contain spaces ?

PostgreSQL 6.4 on RedHat Linux i386, 2.0.36 Kernel

THE FIRST ONE
=============
test=>create table students (id int4, name text); 
CREATE
test=> create view "my view" as select * from students;
CREATE
test=> select * from "my view";
ERROR:  nodeRead: Bad type 0 


THE SECOND ONE
==============
test=> create sequence student_id;
CREATE
test=> create table "my students" (id int4 default
nextval('student_id'), name text);
ERROR:  my: Table does not exist.
