Hi [~shv],Thanks for your sincere suggestions,This is my first time to participate in community
issues,I'm sorry.I will submit a new patch according to your opinion.
{quote}     3. Do I understand correctly that with your patch Observer will still be considered
as a target for             failover?

yes, in my cluster,when standby is not healthy, Observer will be allowed to participate in
failover,But this is not in line with your plan,I will correct it,thank you very much.
