weird problem with PG 8.1

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?
