My 2 cents:  I'm somewhat new to PostgreSQL and sysadmin'ing in general,
but I haven't had problems with installs/upgrades.

The reason:  I haven't used the RPMs, I went the "hard" route and did
builds and installs.  This, in turn, forced me to read the
install/upgrade documentation (very well written, kudos to the authors
-- very good section on system config, too) which I would never have
done if I had done an RPM-style upgrade.

Given the complexity of a DB system (especially if used for heavy work)
and the clarity of the docs, I strongly recommend anyone to scan through
them at least once...
