Internet of Things tends to generate large volumes of data at a great velocity. Often times this data is collected from geographically distributed sources and aggregated at a central location for data scientists to perform their magic i.e. find patterns, trends and make predictions. Let’s explore what the IoT Solution using Postgres-BDR has to offer […]
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 […]

One feature quietly added to PostgreSQL 10 is the ability to determine the commit status of any transaction by transaction-id. It’s reasonable to wonder why you’d want this, since you know if you committed the transaction, it’s still in progress, or if you or rolled it back. And you can check for in-progress transactions in […]
During the Postgres Open 2017 conference in San Francisco, someone came to the 2ndQuadrant booth and struck up a conversation with me. During our shameless geeking out over database mechanics, he asked me if pglogical supported the new Postgres 10 partitions. Given my noted expertise in all things Postgres, I answered in the appropriate manner: […]
1. Introduction Logical replication uses a publish/subscribe model and so we create publications on the upstream (or publisher) and subscriptions on downstream (or subscriber). For more details about it, please refer to this blog post from my colleague Petr Jelinek, and also to the PostgreSQL documentation. Here we will show how to build a test […]
