Date style handling changes between 7.4.12 and 8.2.4

Hi,

I am upgrading from 7.4.12 to 8.2.4 and I have run into a difference in date
style handling...

In 7.4.12 this would work

bugasbase2=# create table date_test (name date);
CREATE TABLE
bugasbase2=# insert into date_test values('Wed Jul 11 10:51:14 GMT+01:00
2001');

However in 8.2.4 this happens

bugasbase_070529=# create table date_test (name date);
CREATE TABLE
bugasbase_070529=# insert into date_test values('Wed Jul 11 10:51:14
GMT+01:00 2001');
ERROR: invalid input syntax for type date: "Wed Jul 11 10:51:14 GMT+01:00
2001"

I assume something to do with date handling has changed?

I have found date_trunc and extract in the docs, but can't seem to get the
syntax right to get this to work... Is there a function that can convert the
string to be acceptable for 8.2.4?

Thanks in advance
