Downgrading v8.4 database to v8.3 - Mailing list pgsql-admin

Hi,

I use Debian GNU/Linux on various servers. Debian Stable a.k.a. Lenny
comes with PostgreSQL v8.3 while Debian Testing a.k.a Squeeze provides
PostgreSQL v8.4.

I need to move some databases written in Psql v8.4 to the stable
production server running v8.3. I tried pg_dump and pg_restore as well
as PgAdmin3.  I am unable to do so due to the backward
incompatibility. Is there anyway to do this?

Thanks in advance.
