Shayon Mukherjee: pg_easy_replicate Supports Schema Change Tracking During Logical Replication

31. August 2024 - 18:19
I have been meaning to support common DDLs (Data Definition Language) for pg_easy_replicate for quite some time now and I am super stoked that it is now finally out. This new capability addresses one of the limitations of PostgreSQL’s native logical replication, bringing more flexibility to database migrations and replication through pg_easy_replicate. What is pg_easy_replicate? For those new to the project, pg_easy_replicate is a CLI orchestrator tool that simplifies the process of setting up and managing logical replication between PostgreSQL databases.

Tomas Vondra: Office hours experiment

31. August 2024 - 12:00
I’ve decided to experiment a little bit and do regular “office hours.” I’ll be available to chat about almost anything related to Postgres. It might be a technical discussion about a patch you’re working on, or a topic about the community etc. This is not an entirely new thing. I’ve been telling people to just ping me if they want to discuss something off-list, or have a call and chat about it.

Greg Sabino Mullane: Understanding the Postgres Hackers Mailing List Language

29. August 2024 - 21:30

The Postgres hackers mailing list (pgsql-hackers@postgresql.org) is an invaluable resource for anyone wanting to contribute to the PostgreSQL code. The Postgres project does not use PRs (pull requests) or GitHub issues. So if you want to contribute an idea, or help with code reviews, the hackers mailing list is the canonical way to do so.

semab tariq: A Beginner’s Guide to Sharding PostgreSQL with Citus

29. August 2024 - 7:29

PostgreSQL is a powerful and open-source relational database system known for its reliability, flexibility, and advanced features. It handles complex queries, ensures data integrity, and can be extended to meet various needs, making it a popular choice for many applications. However, as your data grows and the number of transactions increases, scaling PostgreSQL can be challenging.

Keith Fiske: Announcing an Open Source Monitoring Extension for Postgres with pgMonitor

27. August 2024 - 16:00

Crunchy Data is pleased to announce a new open source pgMonitor Extension. Crunchy Data has worked on a pgMonitor tool for several years as part of our Kubernetes and self-managed Postgres deployments and recently we’ve added an extension to the tool set.

Two primary scenarios motivated the creation of the pgMonitor extension :

Umair Shahid: PostgreSQL is a viable alternative to Oracle – here is why…

27. August 2024 - 13:23

Why pay $100,000 for something you can achieve in $5,000? That’s the main question. Oracle is a long-standing giant in the DBMS world, offering a feature-rich platform but at a steep price, often catering to large enterprises with extensive budgets. PostgreSQL, on the other hand, is open source with a liberal license and zero licensing fees.

Tomas Vondra: [PATCH IDEA] Using COPY for postgres_fdw INSERT batching

27. August 2024 - 12:00

In an earlier post I mentioned I plan to share a couple patch ideas, suitable for new contributors. This is the first one, about using COPY protocol for postgres_fdw batching. This would replace the current implementation, based on prepared statements. Let me share a couple thoughts on the motivation and how it might be implemented.

Gabriele Bartolini: CNPG Recipe 12 - Exposing Postgres outside Kubernetes with Service Templates

26. August 2024 - 9:38

In this article, I’ll introduce you to the new service template feature in CloudNativePG 1.24, which greatly simplifies the creation of services such as LoadBalancer to expose PostgreSQL outside of your Kubernetes cluster - particularly useful for streamlining Database-as-a-Service (DBaaS) deployments. I’ll walk you through setting up this feature on your laptop using kind and cloud-provider-kind, ensuring you can easily test and implement these capabilities in your own environment.

Radim Marek: Beyond Simple Upserts with MERGE in PostgreSQL

25. August 2024 - 2:00

Understanding how comfortable someone is with databases and SQL often comes down to the features they use. In PostgreSQL, one such feature that distinguishes more advanced users is the MERGE command, introduced in version 15 and expanded in version 17 (in beta at the time of writing this article). Before MERGE, developers typically relied on INSERT ... ON CONFLICT DO UPDATE for upserts—a method introduced in PostgreSQL 9.5 that has since become a staple in many developers' toolkits.

cary huang: How to Utilize PostgreSQL’s JSONB APIs as a Simple JSON Parser for Your Extension

23. August 2024 - 21:19
Introduction

In your PostgreSQL extension development based on the C language, you may come across a need to work with structured data like JSON. Naturally, you would probably introduce a third-party JSON parsers such as cJSON or libjannson in your extension. While they are powerful, easy to use and offering many features, it may be unnecessary if we weren’t fully utilizing the advanced features of these libraries. Many times, we just want to read a particular value from JSON or simply iterating through it.

Tomas Vondra: Importing Postgres mailing list archives

23. August 2024 - 12:00

A couple weeks ago I needed to move my mailing list communication to a different mailbox. That sounds straightforward - go to the community account and resubscribe to all the lists with the new address, and then import a bit of history from the archives so that the client can show threads, search etc.

The first part worked like a charm, but importing the archives turned out to be a bit tricky, and I ran into a bunch of non-obvious issues. So here’s how I made that work in the end.
