Change this in the csv-file with text-tools like sed or awk. Other
solution: use a temp. table for input and use to_date to convert,
simple example:

test=> create table e (d date);
CREATE TABLE
test=*> create table e_temp (d text);
CREATE TABLE
test=*> copy e_temp from stdin;
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>> 30/08/2007
>> \.
test=*> insert into e select to_date(d, 'dd/mm/yyyy') from e_temp;
INSERT 0 1
test=*> select * from e;
d
