no implicit cast error in 9.2?

Hi,

I am using
PostgreSQL 9.2.3 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.6
20120305 (Red Hat 4.4.6-4), 64-bit.

I got a bit confused after installing this version. So far I used to know
that from Postgresql 8.3 implicit casting has been removed and the
following should not work at 8.3 :
create table testtab ( id varchar, id1 int)
insert into testtab values (1,1);

Where it was good to work at 8.1

I also faced the problem earlier.

But in 9.2 it is working perfectly.
Am I missing any release notes?

Please share your opinion. It will be appreciated.

Thanks.
