Bug reference: 5137
Logged by: Peter Bengtson

PostgreSQL version: 8.3.8
Operating system: Debian, Mac OS X
Description: Upgrade policy clarification
Details:
It would be good if you to the page describing how a db dump is required
only for major verson upgrades, e.g. from 8.3.x to 8.4.x but not from, say,
8.3.7 to 8.3.8, could add a proviso: a DB dump *is* necessary when upgrading
from a server compiled for 32 bits even to the same version compiled for 64
bit architectures.
I recently spent about 12 hours getting my development system in order again
after an upgrade from Leopard to Snow Leopard, simply because I believed
your upgrade policy page. It would be nice if other people didn't have to go
through that process.
