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.
