OK, the original message you sent suggested this didn't work either which
was the confusing part. The fact that you have to do a fresh initdb to go
from anything earlier to alpha2 is expected. The fact that you could go
from 8.4 to 8.5-alpha just reflects that nobody made any internal changes
to the database layout between those versions. That it worked was a lucky
oddity, what you're seeing now is the more common situation.
In general, you have to do a fresh initdb for each testing release to make
a database cluster that the new code will talk to. That this changes each
sub-release is one reason these are strictly useful as test releases.
