Updates failing yet saying they succeeded.

I've been having a few problems with PgSQL not updateing data
correctly. Here is some evidence:

autosupply_co_jp=> update vehicle set fob_price =420000 where
chassis_number
autosupply_co_jp-> = 'RA2-1002998';
UPDATE 1
autosupply_co_jp=> select fob_price from vehicle where chassis_number =
'RA2-1042998';
fob_price
-----------
430000
(1 row)

autosupply_co_jp=> update vehicle set fob_price = 420000 where
chassis_number = 'RA2-1042998';
UPDATE 1
autosupply_co_jp=> select fob_price from vehicle where chassis_number =
'RA2-1042998';
fob_price
-----------
420000
(1 row)

WTF is up with that?
