ORDER BY is case insensitive

I was suprised to find out that ORDER BY is case insensitive.  Is
there a way to do a case sensitive ORDER BY clause?

This transcript demonstrates what I am seeing:

$ createdb bryan
$ psql bryan
psql (8.4.4)
Type "help" for help.

bryan=# create table t (f text);
CREATE TABLE
bryan=# insert into t (f) values ('a');
INSERT 0 1
bryan=# insert into t (f) values ('b');
INSERT 0 1
bryan=# insert into t (f) values ('c');
INSERT 0 1
bryan=# insert into t (f) values ('B');
INSERT 0 1
bryan=# select * from t order by f;f
---abBc
(4 rows)

bryan=# \q
~  $ psql -l                                    List of databases     Name       |  Owner   | Encoding |  Collation  |
