Well. Im not really surprised. The column is text, so it sound
reasonable to order by its *text* representation. You may want to order
from its *ascii* value instead:
regression=# SELECT * from test order by ascii(data);
data
------
B
a
b
c
(4 rows)
Or similar...Wich order are you expecting to see?
