After a bit of discussion, the core committee has decided that we're not
really ready to wrap a credible beta1 candidate tomorrow. There are
several unresolved issues such as what to do about checksums and
matviews; and there seems no good reason to force resolution of
these important issues on a tight deadline.
So we'll delay the beta a week. New plan is wrap Monday May 6,
announce Thursday May 9.
