With your patch, this code
now means that in order to finish recovery you need to send SIGUSR2 to
the startup process *and* to create the promote signal file.
Yes, but isn't this the same as the way to trigger fast promotion in HEAD?
Yep, but my point is that some users who have been relying only on
SIGUSR2 sent to the startup process for a promotion may be surprised
to see that doing the same operation does not trigger a promotion
anymore.
Yeah, but that's not documented. So I don't think that we need to keep
the backward-compatibility for that.
Also in that case, non-fast promotion is triggered. Since my patch
tries to remove non-fast promotion, it's intentional to prevent them
from doing that. But you think that we should not drop that because
there are still some users for that?
