Works here:

test(5432)aklaver=>SELECT version();
version
--------------------------------------------------------------------------------------------------
PostgreSQL 9.0.3 on i686-pc-linux-gnu, compiled by GCC gcc (Ubuntu
4.4.3-4ubuntu5) 4.4.3, 32-bit
(1 row)

test(5432)aklaver=> ALTER TABLE mytable2 ADD PRIMARY KEY(id);
NOTICE: ALTER TABLE / ADD PRIMARY KEY will create implicit index
"mytable2_pkey" for table "mytable2"
ALTER TABLE
test(5432)aklaver=>\d+ mytable2
Table "public.mytable2"
Column | Type | Modifiers | Storage | Description
--------+---------+-----------+----------+-------------
id | integer | not null | plain |
name | text | | extended |
Indexes:
"mytable2_pkey" PRIMARY KEY, btree (id)
Has OIDs: no

Note the btree designation.
