Since I can't think of any good reasonto do this, we should simply error out on startup if someone sets things up that way. How can we detect that we'veconnected streaming replication to the same server? It might be easy to detect the situation where the standby has connected to itself, e.g., by assigning ID for each instance and checking whether IDs of two servers are the same. But it seems not easy to detect the circularly-connected two or more standbys. Regards, -- Fujii Masao
