I'm running PostgreSQL 8.0.3 on i686-pc-linux-gnu (Fedora Core 2). I've been
dealing with Psql for over than 2 years now, but I've never had this case
before.

I have a table that has about 20 rows in it.

Table "public.s_apotik"
Column | Type | Modifiers
-------------------+------------------------------+------------------
obat_id | character varying(10) | not null
stock | numeric | not null
s_min | numeric | not null
s_jual | numeric |
s_r_jual | numeric |
s_order | numeric |
s_r_order | numeric |
s_bs | numeric |
last_receive | timestamp without time zone |
Indexes:
"s_apotik_pkey" PRIMARY KEY, btree(obat_id)

When I try to UPDATE one of the row, nothing happens for a very long time.
First, I run it on PgAdminIII, I can see the miliseconds are growing as I
waited. Then I stop the query, because the time needed for it is unbelievably
wrong.

Then I try to run the query from the psql shell. For example, the table has
obat_id : A, B, C, D.
db=# UPDATE s_apotik SET stock = 100 WHERE obat_id='A';
(.... nothing happens.. I press the Ctrl-C to stop it. This is what comes out
:)
Cancel request sent
ERROR: canceling query due to user request

(If I try another obat_id)
db=# UPDATE s_apotik SET stock = 100 WHERE obat_id='B';
(Less than a second, this is what comes out :)
UPDATE 1

I can't do anything to that row. I can't DELETE it. Can't DROP the table.
I want this data out of my database.
What should I do? It's like there's a falsely pointed index here.
Any help would be very much appreciated.

Regards,
Jenny Tania
