Fedora + Yum + 8.1 - Mailing list pgsql-general

I am running Fedora core 4 with nightly "yum" update. Presently it is
not picking up version 8.1 as an upgrade.

1) If I wait will 8.1 get added to the "yummy" list

or

2) If I add 8.1 via the RPMs will future releases be maintained by "yum"
or do future upgrades have to continue to be done manually via RPM's

thanks

Richard
