... So, almost a month has gone by, and we still don't have multirange
unnest(). Looking at the open items list, it doesn't look like we have
anything that would require a catversion bump. Does that mean that
we're going to ship pg14 without multirange unnest?

That seems pretty sad, as the usability of the feature is greatly
reduced. Just look at what's being suggested:

To me this screams of an incomplete datatype. I far prefer a beta3
initdb than shipping 14GA without multirange unnest.

I haven't seen any announcements about beta3, but it's probably not far
off; I think if we're going to have it, it would be much better to give
it buildfarm cycles several days in advance and not just the last
weekend.

What do others think?
