I just ran these:

linux:

on linux

# SELECT CASE WHEN 'apache' > '!yada' THEN 'TRUE' ELSE 'FALSE' END FROM
pg_user;
case
-------
FALSE
(1 row)

# show lc_collate;
lc_collate
-------------
en_US.UTF-8
(1 row)

------------------------

on mac os x:

# SELECT CASE WHEN 'apache' > '!yada' THEN 'TRUE' ELSE 'FALSE' END FROM
pg_user;
case
------
TRUE
(1 row)

# show lc_collate;
lc_collate
-------------
en_US.UTF-8
(1 row)

-----------------------

Why is the linux postgres saying false with the lc_collage set the way it
is?
