#2 seems like a much better choice. A small inconvenience during beta is much 
better than one in the actual release.

People running the beta expects us to try not to force initdb, but also that 
we'll do it if we have to.

Might be worthwhile to try to get beta2 out as quickly as we can after the 
changes are in, to minimize the number of people who will need it?

Absolutely pro.
