Logical decoding and logical replication is getting more attention in the PostgreSQL world. This means we need it working well alongside production HA systems – and it turns out there’s a problem there. Replication slots are not themselves synced to physical replicas so you can’t continue to use a slot after a master failure results […]
I’ve started to write about the tool (pglupgrade) that I developed to perform near-zero downtime automated upgrades of PostgreSQL clusters. In this post, I’ll be talking about the tool and discuss its design details. You can check the first part of the series here: Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud (Part I). The tool is […]
Last week, I was at Nordic PGDay 2018 and I had quite a few conversations about the tool that I wrote, namely pglupgrade, to automate PostgreSQL major version upgrades in a replication cluster setup. I was quite happy that it has been heard and some other people in different communities giving talks at meetups and other […]

BDR has always been an extension, but on 9.4 it required a heavily patched PostgreSQL, one that isn’t fully on-disk-format compatible with stock community PostgreSQL 9.4. The goal all along has been to […]
PostgreSQL is an awesome project and it evolves at an amazing rate. We’ll focus on evolution of fault tolerance capabilities in PostgreSQL throughout its versions with a series of blog posts. This is the fourth post of the series and we’ll talk about synchronous commit and its effects on fault tolerance and dependability of PostgreSQL. […]
