hello expert, I had to do a backup on replication master-slave servers. I also have asked this question before, but I don't understand why I followed the information and same scripting to run on the replication servers and didn't work. I can run pg_dumpall successful but not with the script. Would you please tell me what's wrong and what need to correct the error? my replication server (master) pg_hba.conf # "local" is for Unix domain socket connections onlylocal all all peerhost all all 192.168.2.0/24 trust# IPv4 local connections:host all all 127.0.0.1/32 indentlocal all postgres trusthost all power_user 0.0.0.0/0 md5host all other_user 0.0.0.0/0 md5 host all storageLoader 0.0.0.0/0 md5 # IPv6 local connections:host all all ::1/128 indent#allow replication connections from localhost, by a user with the replication priviledgelocal replication all trusthost replication all 127.0.0.1/32 trusthost replicaiton all ::1/128 trusthost replication replicauser masterIP/32 trusthost replicaiton replicauser slaveIP/32 trust from the postgres prompt I can connect to each database #psql -d template0 -U postgres template0-# #psql -d template1 -U postgres template1-#
