Hi
I have made a lot of PostgreSQL High Availability tests (more
than 20 by solution) and the two following products respond well to the need :
(1) Repmgr (2ndQuadrant)
(2) Pglookout (aiven)
About PAF, the product is hard to install and set up . It need a linux cluster
and a system engineers team to use it.
Best Regards

Objet : increasing HA
Hello,
I am looking after some advice about solution allowing to increase High
availability?
Here is a bit of context :
I have an Master-Slave architecture
- 1 master
- 2 asynchronous slaves using replication slot
- backup is made with barman using replication slot
- Wal archiving is done towards barman server
I think 3 axes could be improved ( I am totaly novice with these):
- using of a proxy
I found HAproxy.
Could you advice any others solutions to explore or share your experience?
- using an automatick failover
I found PAF
Could you advice any others solutions to explore or share your experience?
- using a tool for fencing a failing node
Ideally, I aimagine to disable network traffic in I/O to prevent client
connecting and exchange between backup server failling server + on postgesql
server disable automatic restart of the service.
Could you share you experience about it?
- Maybe an other axe to explore ?
Thank you
Thomas
