Okay:

test=# select * from fruit;
name | fruit
--------+-------
Apple | 1
Banana | 2
Cherry | 3
(3 Zeilen)

test=# select name, fruit, case
test-# when fruit = 1 then 'good'
test-# when fruit = 2 then 'bad'
test-# when fruit = 3 then 'rotten' end from fruit;
name | fruit | case
--------+-------+--------
Apple | 1 | good
Banana | 2 | bad
Cherry | 3 | rotten
