Sure -

  coza=> set datestyle to 'SQL,European';
  SET VARIABLE
  coza=> select registrationdate from accounts where domain = 'flame.co.za';
  registrationdate           
  ---------------------------
  02/06/1997 00:00:00.00 SAST
  (1 row)

The above result is correct for dd/mm/yyyy styles

  coza=> set datestyle to 'ISO,European';
  SET VARIABLE
  coza=> select registrationdate from accounts where domain = 'flame.co.za';  
  registrationdate      
  ----------------------
  1997-06-02 00:00:00+02
  (1 row)

Instead of 02-06-1997 00:00:00+02

If ISO is specific regarding formatting of days, month and year then I feel that
the "set datestyle to 'ISO,European'" should give an error. However, I would
personally
prefer it to format the result as "dd-mm-yyyy".
