On: PostgreSQL HA cluster failure: a post-mortem

[sandGorgon]

>Fortunately, as part of some unrelated work we'd done recently, we had a version of the cluster that we could run inside Docker containers. We used it to help us build a script that mimicked the failures we saw in production. Being able to rapidly turn clusters up and down let us iterate on that script quickly, until we found a combination of events that broke the cluster in just the right way.

this is the coolest part of this story. Any chance these scripts are opensource ?

We plan to open source it as soon as we can. Tiny bit more work to do, then review from a couple of people in the team, then we make it public. :)

Thanks for this !
