I think forcing an initdb might be more trouble than this wart is worth.

I have one or two 9.0-beta databases,  a forced initdb would defiantly
motivate me to try pg_upgrade :).  To me, the question is are  we
planning on releasing a new beta anyway?  Maybe its worth it then.  If
we were planning on going RC after this last beta (and I dont think we
were?), I agree with Kevin, its not something worth pushing the
release 9.0 for.  By that I mean I assume if we force an initdb that
we would want to do another beta regardless.

Either way, I don't have strong feelings on this other than if we dont
fix it now when will we?  Maybe we will get "lucky" and someone will
find an issue that we have to initdb for anyways :).
