Gitlab had some issues recently with PostgreSQL. - http://www.theregister.co.uk/2018/04/27/gitlab_outage_april_2018/ - https://docs.google.com/document/d/1_IzyO-jwqb7UFl0A28D1gR4EaU99cEnoUSD9o8q4eZw/edit# From their timeline report, it looks like they were using repmgr. Somehow, I don't understand how they manage to get split-brain from a primary failure with a 5 node cluster. Does anyone have more insights to this? -- Regards, Ang Wei Shan
