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 conferences about near-zero downtime upgrades using logical replication. Given that there is a talk that I gave at PGDAY'17 Russia, PGConf.EU 2017 in Warsaw and lastly at FOSDEM PGDay 2018 in Brussels, I thought it is better to create a blog post to keep this presentation available to the folks who could not make it to any of the conferences aforementioned. If you would like to directly go the talk and skip reading this blog post here is your link: Near-Zero Downtime (more…)
In Part 2 of this series, we will continue our journey within the developmental dynamics of the Barman open source project for PostgreSQL database backup and disaster recovery.

We very often hear about devops culture, lean and agile methodologies, kanban, pair programming, peer review, testing, and many more; but how many of us could effectively put these things into practice?
