Yet another online event organized by PgTraining!PgTraining online webinar on 2022-04-29 (Italian)
PgTraining, the amazin italian group of people that spread the word about PostgreSQL and that I joined in the last years, is organizing another online event (webinar) on next 29th April 2022.
Following the success of the previous edition(s), we decided to provide another afternoon full of PostgreSQL talks, in the hope to improve the adoption of this great database.

Time-series data is ubiquitous in almost every application today. One of the most frequent queries applications make on time-series data is to find the most recent value for a given device or item.
In this blog post, we'll explore five methods for accessing the most recent value in PostgreSQL. Each option has their advantages and disadvantages, which we'll discuss as we go.
In my previous post I gave an overview of some general parameters that will work well in a standard setting. They might be aggressive, but will allow other processes to work without interruption.

Modern operating systems like linux are really sophisticated. This sophistication means that sometimes things are actually different than they make you believe. One of these things is memory usage.
Linux, like most modern operating systems, use virtual memory. That means that every distinct process has got its address space, which is completely private to the process, and its threads, if it is using threads.
Release note and commit log of Pgpool-II 4.3
In this blog I would like to explain some of new features of the latest Pgpool-II major version 4.3, which was released in December 2021.
I recently investigated one internal issue which was related with snapshot and found there were some changes on transaction id and snapshot information functions in PostgreSQL. Here, I am trying to share what I have learned.
