Streaming replication and an archivelog - Mailing list pgsql-general
Hello All,
James Sewell,
PostgreSQL Team Lead / Solutions Architect
______________________________________
I am running 9.4 on Centos.
I have three servers, one master and two slaves. The slaves have the following recovery.conf
standby_mode = 'on'
primary_conninfo = 'user=postgres host=mastervip port=5432'
restore_command = 'scp -o BatchMode=yes postgres@backuphost:/archived_wals/%f %p'
recovery_target_timeline= 'latest'
Is there any way to combine following
- a master switch (ie: if node1 dies and node2 is promoted then node3 follows node2)
- using a WAL archive, such that if node2 goes down for two days it will get WALs from the archive if they are no longer on the master
At the moment the master switch works fine, but if I was to have a WAL archive with multiple timelines in it then I would end up in the newest timeline.
I suppose what I want is the following:
If I am a streaming replica only follow streamed timeline switches, not archive timeline switches.
Obviously if I am not a streaming replica I need to follow archive timeline switches so I don't break PIT recovery.
Possible?
