Radim Marek: We need to talk about ENUMs

Neues vom PostgreSQL Planet - 4. September 2024 - 2:00

Designing a database schema, whether for a new application or a new feature, always raises a lot of questions. The choices you make can have a big impact on how well your database performs and how easy it is to maintain and scale. Whether you’re just getting started with PostgreSQL or consider yourself a seasoned pro, it’s easy to rely on old habits or outdated advice. In this article, I want to take a fresh look at one of those topics that often sparks debate: the use of ENUMs in PostgreSQL.

Neues vom PostgreSQL Planet - 4. September 2024 - 0:00
Timescale PostgreSQL Survey

Timescale Inc. is a well known company in the PostgreSQL community, mostly because of their PostgreSQL extension TimescaleDB.

The survey for 2024 is open now until September 30th 2024. If you could spare some time to answer the questions, the community would appreciate it.

The results will be published shortly afer the survey has ended to everyone.

Michael Banck: Quick Benchmark: ANALYZE vs. maintenance_io_concurrency

Neues vom PostgreSQL Planet - 3. September 2024 - 15:55
Introduction

Running ANALYZE (either explicitly or via auto-analyze) is very important in order to have uptodate data statistics for the Postgres query planner. In particular after in-place upgrades via pg_upgrade, ANALYZE needs to be run in order to have any query statistics at all. As ANALYZE samples only parts of the blocks in a table its I/O pattern looks more like random access than sequential read.

Tomas Vondra: [PATCH IDEA] Statistics for the file descriptor cache

Neues vom PostgreSQL Planet - 3. September 2024 - 12:00

Let me present another “first patch” idea, related to a runtime stats on access to files storing data. Having this kind of information would be very valuable on instances with many files (which can happen for many reasons).

This is a very different area than the patch idea, which was about an extension. The runtime stats are at the core of the system, and so is the interaction with the file systems. But it’s still fairly isolated, and thus suitable for new contributors.

semab tariq: Deploying Your First PostgreSQL Clusters on Kubernetes with Cloud Native Postgres

Neues vom PostgreSQL Planet - 3. September 2024 - 9:54

CloudNativePG is an open-source operator designed to manage PostgreSQL workloads on any supported Kubernetes cluster running in private, public, hybrid, or multi-cloud environments. CloudNativePG adheres to DevOps principles and concepts such as declarative configuration and immutable infrastructure.

The post Deploying Your First PostgreSQL Clusters on Kubernetes with Cloud Native Postgres appeared first on Stormatics.

Gabriele Bartolini: How to test a PostgreSQL Commitfest patch in Kubernetes

Neues vom PostgreSQL Planet - 3. September 2024 - 9:01

In this article, I’ll explore how Kubernetes and CloudNativePG can be leveraged to streamline the testing of PostgreSQL patches, especially during a Commitfest. By automating the creation of PostgreSQL container images from any public Git repository, developers and reviewers can quickly and efficiently test patches within a Kubernetes environment. This approach not only saves time but also enhances the reliability of patches before integration into the main codebase.

Hans-Juergen Schoenig: VACUUM: Managing and detecting bloat

Neues vom PostgreSQL Planet - 3. September 2024 - 9:00

In this introduction, we will explore the concept of VACUUM in PostgreSQL, its importance, and best practices for implementing effective vacuuming strategies to ensure your database remains efficient, performant, and reliable. Before we dive into strategies, problem detection and so on, it is important to understand why VACUUM is needed in the first place.

Peter Eisentraut: PostgreSQL LTO battle

Neues vom PostgreSQL Planet - 3. September 2024 - 6:00

I wrote recently about the performance of PostgreSQL when compiled with different compilers and optimization levels. Another dimension in that evaluation is link-time optimization (LTO).

LTO allows the compiler to perform optimizations across source-file boundaries (more correctly, compilation unit boundaries).

Henrietta Dombrovskaya: “Sometimes, It’s Slow!”

Neues vom PostgreSQL Planet - 2. September 2024 - 17:52

These are my least favorite mysteries to resolve. I hate mysteries when it comes to performance problems. A performance mystery means I do not know how to make it work faster! However, I love solving mysteries—except when presented with a “sometimes it is slow” case.

Shayon Mukherjee: pg_easy_replicate Supports Schema Change Tracking During Logical Replication

Neues vom PostgreSQL Planet - 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

Neues vom PostgreSQL Planet - 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.

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

Neues vom PostgreSQL Planet - 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.
