Re: [HACKERS] create table and default 'now' problem ?

One way around this bug is to create a SQL function
which returns now() and use it as the default value:

1. create function mynow() returns datetime
as 'SELECT now()::datetime' LANGUAGE 'SQL';

2. create table test (a datetime default mynow(), b
int4);

Now things should work:

insert into test (b) values (1);
insert into test (b) values (2);

select * from test;
a |b
----------------------------+-
Tue Sep 21 01:05:02 1999 EDT|1
Tue Sep 21 01:05:08 1999 EDT|2
(2 rows)

Hope this helps,
