Default Timestamp 'Now' bug with 7.4 on Panther.

Running Postgres 7.4 on Panther, there seems to be a problem with
setting a timestamp column to have a default of 'now':

createdb test

create table bar (date timestamp DEFAULT 'now');
insert into bar DEFAULT VALUES;
insert into bar DEFAULT VALUES;
insert into bar DEFAULT VALUES;
insert into bar DEFAULT VALUES;

select * from BAR;


output:

             date
----------------------------
  2004-02-12 15:17:38.838411
  2004-02-12 15:17:38.838411
  2004-02-12 15:17:38.838411
  2004-02-12 15:17:38.838411

All rows have the same timestamp, as if 'now' was interpreted at the
time of table creation, not at the time of insertion.

thanks,

Harry
