Neues vom PostgreSQL Planet

Tembo was founded in December 2022 with a mission to make the best Postgres service to deploy extensions. That mission has evolved since then to provide optimized Postgres instances for your workload, but let’s go back to the start. At the very minimum, we wanted our users to be able to come to Tembo Cloud, create a new Postgres instance, install Postgres extensions into that instance, and connect to that Postgres instance over the public internet.

In my last post I did a quick check on the performance of the newer (lz4, zstd) pg_dump compression options, which included setting up a small framework to download some openly available “real life”-ish sample datasets. And the general result was that, indeed - the new algos in lower levels...

PostgreSQL is very good at keeping your data safe so it doesn’t disappear by itself. Unfortunately, the same holds in reverse–if data has been deleted, it stays unrecoverable.
In this article, we’ll explore options for recovering deleted data from PostgreSQL tables.

Option 1: cautious people use transactions

If you never make any mistakes when working with data, there won’t be any need for emergency procedures. But since we are all human, things like this happen:

We had such thoughtful and engaged discussion at this week’s Postgres Extension Ecosystem Mini-Summit! I did learn that one has to reserve a spot for each mini-summit individually, however. Eventbrite sends reminders for each one you sign up for, not all of them.

The PostgreSQL roles and privileges system can be full of surprises.

Let’s say we have a database test, owned by user owner. In it, we create a very secret function f that we do not want just anyone to be able to execute:

The CFP for the 2024 PASS Data Community Summit is currently open, and we need you! Hosted in Seattle from November 4-8, we want to encourage even more participation from the PostgreSQL community this year. By many accounts, including the State of the Database Landscape report, PostgreSQL continues to be a required skill in new ... Read more

PostgreSQL Person of the Week Interview with Grant Fritchey: I’ve been working in IT for over 30 years. From support to development to database administration, I’ve covered a lot of ground. I was born in the US in Missouri and grew up there and in Oklahoma. I lived all over the country while I was in the Navy and finally settled in Massachusetts where I raised two kids before moving back to Oklahoma to get away from the snow.

Introduction

When you send a query to PostgreSQL, it normally would go through stages of query processing and return you the results at the end. These stages are known as:

The tl;dr of this post is that the CFP is open until April 7th 2024 for POSETTE: An Event for Postgres, the free & virtual developer event brought to you with 🧡 by our Postgres team at Microsoft. Formerly called Citus Con.

Last Phriday we explored just where Postgres could end up in the future. One possible question which may have occurred to a reader was probably something along the lines of “That doesn’t even really sound like Postgres anymore. Why not just write another database?” Let’s just be outright about it: Postgres is the best RDBMS engine currently available. It’s certainly bold to claim that any database engine is “the best”, and as the saying goes, “Extraordinary claims require extraordinary evidence.

The article explores the deployment of pgAdmin4, a popular graphical user interface for PostgreSQL, within a CloudNativePG environment, primarily for evaluation and educational purposes. The process involves deploying pgAdmin4 to connect to a PostgreSQL cluster, navigating its interface, and utilizing SQL functionality. The article provides detailed deployment instructions and highlights the use of the --mode desktop option for seamless integration.

PostgreSQL “extensions” are a big part of what makes this database special.

This post proposes a new metadata standard for extension packaging, distribution, and delivery, building on the PGXN Meta Spec to address its shortcomings and emerging use cases 12 years on. The goals include:

The blog describes all the steps required to safely migrate your Heroku PostgreSQL database to self managed PostgreSQL on AWS EC2 instance using logshipping method.

We at Fujitsu have been actively contributing to the PostgreSQL opensource community since 2003, participating in the development of new features, bug fixes, and code review. Today I would like to talk about what a typical day is like as a Postgres engineer.

 

A few changes to a part of pgagroal.

pgagroal-cli minor bug fixes

In the past days I pushed a few troophy patches to pgagroal-cli, the command line tool to administer a pgagroal connection pooler, in order to fix minor issues that produced unattended results.

The bug were all harmless, since they only affected what the pgagroal-cli was producing as output to the user, but could have been confusing for some use cases, hence the need to fix them.

I compiled and uploaded zip files with latest orafce and plpgsql_check for PostgreSQL 15 and PostgreSQL 16.

Setup:

PostgreSQL has emerged as a reliable, feature-rich database used extensively across various industries. On the other hand, Go (Golang), known for its simplicity, efficiency, and strong standard libraries, has become increasingly preferred for modern backend development. In this article we will discuss PGX – a powerful, lightweight, and easy-to-use driver for accessing PostgreSQL databases in […]
