Обсуждение: SR: "pseudo replication database of the primary" ...
I'm reading through the Wiki docs, and one thing isn't clear: "3. Set up connections and authentication so that the standby server can successfully connect to the pseudo replication database of the primary." I've searched Google, to see if its mentioned anywhere else, but nadda ... can't connect to it using psql, which makes it confusing as to why I'm configuring access to it via pg_hba.conf ... So, what am I missing that should be obvious to me ... ? ---- Marc G.

Yeah, since there is no 'replication' database unless user explicitly creates it, psql would be unable to connect to it. 'replication' is the keyword of pg_hba.conf only for authenticating the standby server. This keyword needs to be specified in the 'database' field of pg_hba.conf. So I expressed it as the pseudo replication database. Please see the document for details. http://developer.postgresql.org/pgdocs/postgres/streaming-replication.html#STREAMING-REPLICATION-AUTHENTICATION http://developer.postgresql.org/pgdocs/postgres/auth-pg-hba-conf.html If that expression is confusing, please feel free to modify it in the wiki and doc ;) Regards, -- Fujii Masao NIPPON TELEGRAPH AND TELEPHONE CORPORATION NTT Open Source Software Center

I also changed the expression on wiki so. Regards, -- Fujii Masao NIPPON TELEGRAPH AND TELEPHONE CORPORATION NTT Open Source Software Center
My only thought would be to change 'pseudo' to 'virtual' ... my initial read, I was looking for a system database like template1/template0 being created ... Thx ...
