You need to warn people about updating with centosplus enabled, otherwise if 
they use centosplus (for perhaps the unsupported kernels or PHP5) and they 
have a running PostgreSQL instance, they will get a nasty surprise.

To the OP, a major PostgreSQL version jump/upgrade is virtually impossible to 
automate within the constraints of the RPM mechanism (and yum/up2date do not 
change the underlying mechanism, except perhaps the order in which triggers 
fire and scriptlets execute, but I've not tested that).  You need to know to 
do a full backup/dump and wipe the database dir before the upgrade, then do 
your restore.  Database upgrades are not easy; PostgreSQL, because of the way 
and depth in which it can be extended can be more difficult than most, but 
that's due to its power.
