Yeah, more than likely :-(.  Could we see a stack trace from the
segfault?

Hmm.  There is a known bug in beta2 that's triggered by old and new
clusters not having the same name for the bootstrap superuser; although
I don't recall that the symptoms included a segfault.  In any case,
I'd suggest making sure the new cluster is initdb'd under the same
account that currently owns the old cluster.
