Hi, I'm a postgres newbie (in fact a DB newbie if I'm honest :))
I'm just wondering if there is a way to slave from a slave server? I have a Postgres9.1.3 master serving up data quite happily to the web applications, and I have also set up a slave via streaming replication. I've now been asked by my manager to set up a secondary slave, slaving off the first slave - e.g. Master (DB1) --> Slave (DB2) --> Secondary_Slave (DB3) Is there an easy way to accomplish this? In my tests last night I setup the DB3 server to replicate from DB2, but for some reason it was complaining about 'max_wal_senders' being set to 1 on the master. If all the settings are pointing DB3 at DB2, why would it be trying to talk to DB1 instead? Cheers, Rob.
