Your name : Hannes Wenzel
Your email address : hannes.wenzel@aon.at

System Configuration
- ---------------------
Architecture (example: Intel Pentium) : Intel Pentium III, 1133 MHz

Operating System (example: Linux 2.0.26 ELF) : Linux 2.4.20 ELF

PostgreSQL version (example: PostgreSQL-7.3.2): PostgreSQL-7.3.2

Compiler used (example: gcc 2.95.2) : gcc 3.2.3

Please enter a FULL description of your problem:
- ------------------------------------------------
A select with a to_char function to convert number to formated output with
locale support produces wrong group seperator characters.
The to_char function show a ',' as group seperator and ',' as decimal point.
So the group seperator is wrong, the decimal point is ok.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
- ----------------------------------------------------------------------
Created a database cluster with:

# initdb --pgdata=/home/postgres/db/home --locale=de_AT.iso885915@euro
- --username=han

then the database with:

# createdb --owner han home

The Unix user id is 'postgres' the LANG environment variable was set to
'de_AT.iso885915@euro'.

The description of the corresponding table is:

home=# \d eur
Tabelle »public.eur«
Spalte | Typ | Attribute
- --------+-----------------------------+-----------------------------------------------------
id | integer | not null default
nextval('public.eur_id_seq'::text)
datum | timestamp without time zone | not null
curr | integer | not null
val | numeric(15,5) | not null
Indizies: eur_pkey Primärschlüssel btree (id)
Foreign-Key-Constraints: $1 FOREIGN KEY (curr) REFERENCES currency(id) ON
UPDATE NO ACTION ON DELETE NO ACTION

Inserted some values into the table. The following select shows the following
output:

home=# select val,to_char(val,'999G999G990D00') from eur;
1719000.00000 | 1,719,000,00
1389.50000 | 1,389,50
37737.00000 | 37,737,00
1737000.00000 | 1,737,000,00

The correct output should be as follows:

1719000.00000 | 1.719.000,00
1389.50000 | 1.389,50
37737.00000 | 37.737,00
1737000.00000 | 1.737.000,00

Feel free to contact me per e-mail if you have further questions.
