Although we have some different settings in pg_hba.conf in different clusters, but both at least allows local connection to ::1. Specific to each cluster, there are some other databases upgraded/restored in the same cluster without this problem, but only "template1" reported this error. I attached some another log file recorded. There may be a possibility some tables were created in the cluster with older pg_hba.conf settings, and then pg_hba.conf changed afterwards. Would this situation possibly caused the reported error? Best regards, Ken
