[GENERAL] problem with dots in order by

[Ruben Oliveira]

Hello everybody !
I have this order by :
select lalala from tablex order by field_y;
where field_y is a text column.
that returns something like :
2.1004.11
21.00.461
2.1006.21
in  PostgreSQL 7.3.2 in Linux Mandrake 9.1
but in PostgreSQL 8.0.0 in Windows XP it works as I expected ...
2.1004.11
2.1006.21
21.00.461
the two config share the same Encoding when the database was created and 
the client enconding is the same in the two cases :

H:\Documents and Settings\User>psql -l -U postgres
       List of databases
  Name    |  Owner   | Encoding
-----------+----------+-----------
bd2005    | postgres | SQL_ASCII
Can anybody tell me if there is something I can do in the Linux config 
to have the same order by result ??
Using XP is only for tests... I love my Mandrake server :P
