pgsql 7.4b2 bug on column defaults?

Hi,
just testing beta2 I got strange things on default values with functions:

create table test2 (i integer, t timestamp default 'now()');

test1=# \d test2
Table "public.test2"
Column | Type |
Modifiers
--------+-----------------------------+-------------------------------------------------------------------
i | integer |
t | timestamp without time zone | default '29/08/2003
11:26:23.937421'::timestamp without time zone

test1=# insert into test2 values(1);
INSERT 9841455 1
test1=# insert into test2 values(1);
INSERT 9841456 1
test1=# insert into test2 values(1);
INSERT 9841457 1

test1=# select * from test2;
i | t
---+----------------------------
1 | 29/08/2003 11:26:23.937421
1 | 29/08/2003 11:26:23.937421
1 | 29/08/2003 11:26:23.937421
(3 rows)

Seems that functions are valuated when the table is created,
It is a known change or a bug ?

thanks,
Giuseppe
