8.4 RPMs

Sorry if this is the wrong list, I'm not totally up with the PG ecosystem.

I'm looking for RHEL/CentOS RPMs for version 8.4 for testing purposes
(with Drupal). I can find an RPM to install a yum repo at
yum.pgsqlrpms.org, but not the RPMs themselves. The yum repo is not much
use to me as the machine I want to install on is not connected to the net.

www.postgresql.org/ftp has 8.3 RPMs, but no 8.4. I know the 8.4 RPMs
must exist somewhere if they're in the pgsqlrpms repo, but where?

Thanks

Mick
