My apologies. I had been under the impression that the go-no window
was between stamp and tag and *that* was the window that was used for
a buildfarm cycle. It sounds like it's not quite as black and white as
that. I'm not aware of any documentation which gives guidance on
this.

I'm only aware of:
* https://wiki.postgresql.org/wiki/Release_process
* https://wiki.postgresql.org/wiki/Committing_checklist

Is there somewhere else I should look? or is this something that can
maybe be improved?

(I'm assuming backing the patch out now won't improve the situation,
but please correct me if you think I'm wrong on that)

Thanks

David
