Ryan Booz: Using Common Table Expressions: Transforming and Analyzing Data in PostgreSQL, Part 2

8. April 2024 - 20:57

In the first article in this transforming data series, I discussed how powerful PostgreSQL can be in ingesting and transforming data for analysis. Over the last few decades, this was traditionally done with a methodology called Extract-Transform-Load (ETL) which usually requires external tools. The goal of ETL is to do the transformation work outside of the database and only import the final form of data that is needed for further analysis and reporting.

Gabriele Bartolini: CloudNativePG Recipe 6: Postgres Vertical Scaling with Storage - part 1

8. April 2024 - 19:37

Are you worried that PostgreSQL cannot scale writes within a single node, or do you think that scaling PostgreSQL can only be done horizontally, across different Kubernetes nodes? Discover the surprising truth behind PostgreSQL’s vertical scalability in this first article of a two-part series. Explore the potential of optimizing CPU, RAM, and storage resources through meticulous measurement and benchmarking, challenging conventional scaling wisdom.

Andreas 'ads' Scherbaum: Jonah H. Harris

8. April 2024 - 16:00
PostgreSQL Person of the Week Interview with Jonah H. Harris: Hello! I’m Jonah, the Founder of NEXTGRES. I’ve been a database enthusiast, user, administrator, and developer for many (many) years. Most people who know me know I approach database selection pragmatically, focusing on the needs of the customer, company, or application rather than ideology. That said, Postgres has (obviously) emerged as my preferred choice over time.

Shaun M. Thomas: PG Phriday: Wanton Animal Cruelty

4. April 2024 - 21:11
The last few PG Phriday articles have been somewhat dense content, so how about something a bit more irreverent? Rather than wax on about AI, HA architectures, or conceptual advancements to Postgres clusters, why not write a game instead? To keep things simple, let’s just build a no-frills Tamagotchi virtual pet for bored database professionals. There’s a lot of SQL in this article, so check out the git page for this blog if you want to follow along.

Emel Şimşek: PgBouncer Connection Pooler for Postgres Now Supports More Session Vars

4. April 2024 - 19:50

PgBouncer is probably the most popular connection pooler for Postgres. It is essentially a transparant middleware between clients and the server. However, it is not %100 transparent in practice. There are a few intricacies that should be taken into account when using PgBouncer. One such consideration is that PgBouncer does not support the use of all session variables in transaction pooling mode. This lack of support is one of the reasons that the most commonly used transaction pooling mode is not fully compatible with Postgres.

Craig Kerstiens: Row Level Security for Tenants in Postgres

3. April 2024 - 15:00

Row-level security (RLS) in Postgres is a feature that allows you to control which rows a user is allowed to access in a particular table. It enables you to define security policies at the row level based on certain conditions, such as user roles or specific attributes in the data. Most commonly this is used to limit access based on the database user connecting, but it can also be handy to ensure data safety for multi-tenant applications.

Álvaro Hernández: Why Postgres Extensions should be packaged and distributed as OCI images

2. April 2024 - 19:17

There is an ongoing and engaging open discussion in the Postgres Community around the future of Postgres extensions. At OnGres we have been operating for around three years a Postgres distribution and repository with around 200 extensions for StackGres, a fully-featured open source platform for self-hosting Postgres on Kubernetes.

David Wheeler: What’s Happening on the PGXN v2 Project

2. April 2024 - 16:00

Since writing about jobs to be done last month, work has continued apace on the project now code-named “PGXN v2”. This effort has encompassed investigating a number of technical questions and decisions, with a few essays and RFCs circulated amongst the PostgreSQL community, as well as a series of talks and discussions around these issues. Here’s a quick update.

Hans-Juergen Schoenig: Performance tuning: MAX and GROUP BY

2. April 2024 - 10:22

These days everybody is talking about time series, time series analysis and alike for performance tuning. Analyzing time series data in PostgreSQL can provide valuable insights, help in making informed decisions and understanding data more deeply. By utilizing PostgreSQL’s powerful features, we can efficiently query all types of measurement data to track trends, patterns, and anomalies over time. However, often there is a tiny little requirement, people are struggling to understand. Consider the following data:

Laurenz Albe: Syslog logging with journald in PostgreSQL

Logging to syslog is not a new PostgreSQL feature at all. Still, I find few people using it, so perhaps an introductory tutorial will be helpful. Since today’s Linux distributions normally use journald for logging, I’ll focus on that.

Syslog terminology

Syslog is the de-facto logging standard on Unix systems. A syslog daemon receives messages from processes and processes them according to its configuration.

Sai Srirampur: Exploring versions of the Postgres logical replication protocol

1. April 2024 - 18:57
Introduction Logical Replication is one of the many ways a Postgres database can replicate data to other Postgres database (a.k.a standby). Logical replication directly reads from the write-ahead log (WAL), recording every database change, avoiding t...
