I strongly disagree with you too :)

Well, most production setups should have some form of replication,
because hardware can fail.

Basically, you need to deal with the hardware failure case anyway, or
you can accept the dump&reload waiting time anyway (because that's
what you would be doing after a hardware failure). Now some nice
replication packages like slony allow for easy upgrading.
Plus as an addon, you get an exercise in switchover handling, that you
can plan ahead.
