The following bug has been logged online:
Bug reference: 2314
Logged by: L.Jumadi
Email address: j0e(at)telkom(dot)net
PostgreSQL version: 8.1.3
Operating system: SimplyMepis 3.4.3 with kernel 2.6.15.2
Description: The Order changed?
Details:
I have a table named test with field like this:
ocode varchar(8), code varchar(8) with primary key
at ocode.With data like this:
ocode code
'test' '-0'
'test' '-1'
'test' '1'
'test' '2'
I give the command in the psql like this:
SELECT * FROM test ORDER BY code;
the result is like this:
ocode code
test -0
test 1
test -1
test 2
When I use 8.0.1 version this command gives me result
like this
ocode code
test -0
test -1
test 1
test 2
The question is this a bug?or there is changes in the
way postgreSQL order the field? Thank's in advance

The most likely explanation is that the locale choice at initdb time for
the two versions was different. The 8.0 result looks consistent with "C"
locale and the 8.1 with some others (like en_US).
For example:
[sszabo(at)dev test]$ cat file
-0
-1
1
2
[sszabo(at)dev test]$ LANG="C" sort file
-0
-1
1
2
[sszabo(at)dev test]$ LANG="en_US" sort file
-0
1
-1
2
