Hi All, I have a very basic question about streaming replication feature of Postgres. Let's assume I have servers A, B, C, D, & E with postgres installed with streaming replication as follow: A --> B ( sync replication ) A --> C ( async replication ) A --> D ( async replication ) A --> E ( async replication ) A is master & rest are slaves.
Now my question is: Assume replication link between A & B may/may not stable. If A goes down, how will I choose my new master from slaves? What are criteria to choose new master? Thanks, Sacheen Birhade
