BUG #1330: Incorrect String Order By In tr_TR Locale

The following bug has been logged online:

Bug reference:      1330
Logged by:          Özgür Çaycı

Email address:      ozgur@cayci.org

PostgreSQL version: 8.0 Beta

Operating system:   Debian Woody

Description:        Incorrect String Order By In tr_TR Locale

Details:

I use 8.0 Beta-5.

I am using a PostgreSQL cluster which I have created with locale tr_TR. When
I use "Order By", the strings are not ordered correctly. The spaces are
ignored when I use "Order By" clause. Here is a sample SQL dump to re-create
this situation:

CREATE TABLE mytable (
    mytext character varying(255)
);

INSERT INTO mytable VALUES ('Güngör, Ahmet');
INSERT INTO mytable VALUES ('Güngör, Bengi');
INSERT INTO mytable VALUES ('Güngördü, Ersin');
INSERT INTO mytable VALUES ('Güngören, Bora');
INSERT INTO mytable VALUES ('Güngör, Erhan');
INSERT INTO mytable VALUES ('Güngör, Erol');

When I try 'Select * FROM mytable ORDER BY mytext ASC'

I get the following output:

Güngör, Ahmet
Güngör, Bengi
Güngördü, Ersin
Güngören, Bora
Güngör, Erhan
Güngör, Erol

The expected result is as follows:

Güngör, Ahmet
Güngör, Bengi
Güngör, Erhan
Güngör, Erol
Güngördü, Ersin
Güngören, Bora

Upgrade to latest glibc. Debian unstable does not have this problem.
