This is not exactly unusual.  You should first check to see if
lc_collate is set differently in the two installations --- but even if
it's the same, there are often platform-specific interpretations of
the sorting rules.  (Not to mention that OS X is flat out broken when
it comes to sorting UTF8 data ...)


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?
