weird problem with PG 8.1

[Marcin Krol <mrkafk(at)gmail(dot)com>]

Hello everyone,

I'm having this completely weird problem that ORDER BY doesn't seem to 
work correctly in PG 8.1 as bundled in RedHat 5.

When I issue:

SELECT * FROM virtualization;

I get all the fields:

reservations=# SELECT * FROM virtualization;
 id | Virtualization  |  color
----+-----------------+---------
  1 | BOX             | #FAFAFA
  2 | LPAR            | #999999
  3 | BOX ZONE HOST   | #FAFAFA
  4 | NPAR            | #9966CC
  5 | VPAR            | #9966CC

But when I try to order by column Virtualization:

reservations=# SELECT * FROM virtualization ORDER BY Virtualization;

ERROR:  could not identify an ordering operator for type virtualization
HINT:  Use an explicit ordering operator or modify the query.


The 'virtualization' table is just a normal table with VARCHAR column of 
Virtualization:

reservations=# \d virtualization
                                  Table "public.virtualization"
     Column     |       Type        |                          Modifiers
----------------+-------------------+-------------------------------------------------------------
 id             | integer           | not null default 
nextval('virtualization_id_seq'::regclass)
 Virtualization | character varying |
 color          | character varying |
Indexes:
    "virtualization_pkey" PRIMARY KEY, btree (id)


When I try to specify table.column I get this:

reservations=# SELECT * FROM virtualization ORDER BY 
virtualization.Virtualization;
ERROR:  column virtualization.virtualization does not exist



What's going on?
