decimal point - european format

 Hello,

 I am from Belgium (Europe) and this is my problem with postgres:

   SET DATESTYLE TO 'ISO';

 Ok, that's what I want for the date  (2001-04-29)
 but the format for the floating point number is not correct.

   1.05 should be 1,05

 How do I solve this ???

 (nothing found on google on this subject)


 Thanks for you time,

Pierre.
