Sean, I saw your email on PostgreSQL general list about replication. We are using 9.1.1 and were having the same issue, unable to setup replication even though following wiki precisely. I was able to setup replication following wiki steps using PG 9.0.3, but not 9.1.1. Then I found this page: http://www.postgresql.org/docs/9.1/static/role-attributes.html where it says: initiating replication A role must explicitly be given permission to initiate streaming replication. A role used for streaming replication must always have LOGIN permission as well. To create such a role, use CREATE ROLE name REPLICATION LOGIN. Does that mean "postgres" superuser is no longer able to also be a replication user in 9.1? If so this is not yet updated on the Replication wiki. I went to the master and created a new user specifically for replication: CREATE ROLE REPLICATOR REPLICATION LOGIN PASSWORD '....'; Then changed my master's pg_hba.conf, and slave's recovery.conf to reference the new user "replicator" instead of "postgres", and I no longer get the same error, and our replication is working. Hope this helps! Thanks, ____ Konstantin Gredeskoul Principal Ruby Engineer ModCloth, Inc.
