All;
We have a 3 node replication setup:
Master (node1) --> Cascading Replication Node (node2) --> Downstream
Standby node (node3)
We will be deploying WAL archiving from the master for PITR backups and
we'll use the staged WAL files in the recovery.conf files in case the
standbys need to revert to log shipping.
Question: whats the best way to ensure consistency of WAL archiving in
the case of changes (failover, etc)? can we setup the cascade node to
archive wals only if it's the master? is this a case where we should
deploy repmgr?
Thanks in advance
