Thread: Postgres Automated Failover

Postgres Automated Failover

From
AI Rumman
Date:
Hi,

I am planning to use Postgresql with TimescaleDb extension. I have to design a system similar to AWS RDS which supports automated failover, transparent minor version upgrades etc.
In early days, I worked with PgPool II to enable heartbeat between the Postgres servers. Is there any new tool to achieve the same by which I can design a transparent failover system for Postgres?

Also is there any multi-master Postgresql solution? Is Postgres-XC production ready?

Any suggestions is appreciated. 

Thanks.

There is multiple HA solutions, none are "transparent failover" though. They
are just automated-failover. A rollback-ed transaction because of failover will
never be transparent from the application point of view.

Look at Patroni or PAF, depending on what you want to achieve.

Hi,

In my opinion repmgr it's worth a look.
