Hi,
I have a "little" problem with data insertion.
Suppose I have a table with a column real for exemple:

CREATE TABLE number (value real);

I want to do something like this

insert into number(value)values('123,5');

but this raise an error because the comma is interpreted not as decimal separator
(the error is "invalid input syntax for type real" ). I have already tryed
to localize all configuration in postgresql.conf.  Those are configurations
I have setted:

# - Locale and Formatting -

datestyle = 'european'
#timezone = unknown        # actually, defaults to TZ environment setting
#australian_timezones = false
#extra_float_digits = 0        # min -15, max 2
#client_encoding = sql_ascii    # actually, defaults to database encoding

# These settings are initialized by initdb -- they might be changed
lc_messages = 'Italian_Italy.1252'        # locale for system error message strings
lc_monetary = 'Italian_Italy.1252'        # locale for monetary formatting
lc_numeric = 'Italian_Italy.1252'        # locale for number formatting
lc_time = 'Italian_Italy.1252'            # locale for time formatting


I have already tried to re execute the initdb but still not works.  So can
be changed the be behaviour of the string parser? How can I set a default
behaviour to parse the comma as a decimal separator?

Note that I cannot known (whe I ran the insert query) the type of the column.

Thanks to all
Luca
