I agree. We should have kept it in experimental until the release
candidate and prepare the extensions there, like in earlier releases.

This is a rather awkward position for upgraders to be in, as we
essentially cannot automate this robustly. This is exactly the reason
why we introduced the p-common infrastructure more than a decade ago,
as trying to do the dumping/restoring in maintainer scripts led to an
eternal stream of upgrade failures and some data loss. But
pg_upgradecluster can't help us with this situation, as we cannot
install beta 2 and 3 in parallel.

So I think the best we can do here is to document how to do the
upgrade, and then not repeat the premature release of betas to
unstable?

Thanks,

Martin
