As Scoot wrote: This is **not** yum's fault. It is your fault actually.
Even if you did this upgrade from sources, it would still be broken.
PostgreSQL does not guarantee not to change on-disk data structure
between development snapshots.

Also, please take a look at here:

http://yum.pgsqlrpms.org/rpmchart.php

As you can see, I already marked 8.4 as not suitable for production,
which is already marked as the same by PostgreSQL developers.

I've been pushing RPMS for testers only, so please be careful when you
use any development PG packages next time.
