David Wheeler: POC: PGXN Binary Distribution Format

20. Juni 2024 - 21:28

In an effort to make discussion of PGXN and related improvements as accessible as possible, I’ve set up PGXN Discussions on GitHub. Of course GitHub created default categories for all sorts of conversation, and all is welcome, in accordance with the PostgresSQL Code of Conduct.

Tomas Vondra: Prague PostgreSQL Developer Day 2024 conference recap

19. Juni 2024 - 21:32

The sixteenth year of the Prague PostgreSQL Developer Day (P2D2) conference, organized by the local PUG, happened on June 4-5. This year EDB was one of the main sponsors of the event, so let us share a brief summary from the conference overall, and a bit more details about contributions by EDB speakers.

Andreas Scherbaum: Understanding VACUUM, VACUUM template0, and Transaction ID Wraparound

19. Juni 2024 - 18:09

PostgreSQL uses Multi-Version Concurrency Control (MVCC) to manage concurrent access to the database, and store each version of a tuple in a table. To keep the database efficient, PostgreSQL employs a cleanup process called VACUUM, which removes unnecessary tuples. This not only saves disk space and keeps the database size under control, it also prevents the dreaded “Transaction ID Wraparound” issue. Regularly running VACUUM is crucial, including on the template0 database, which is normally handled by the Autovacuum daemon.

Shane Borden: Reduce Vacuum by Using “ON CONFLICT” Directive

18. Juni 2024 - 21:08

I’m always working with customers migrating from Oracle to PostgreSQL. One of the things in Oracle that didn’t necessarily have any additional impact other than I/O against an index was if the application executed insert statements which violated a PK constraint. Typically an exception handler was added to the code and while you could argue that the application shouldn’t do that, it typically was not something that had to be dealt with too often. However in PostgreSQL it IS something you need to be aware of.

David Wheeler: Compiling Postgres with LLVM

18. Juni 2024 - 20:45

A quick post on the need to use a compatible Clang compiler when building Postgres with LLVM support. TL;DR: always point the CLANG variable to the correct Clang binary when compiling Postgres --with-llvm.

David Wheeler: 🏔 Extension Ecosystem Summit 2024

The PostgreSQL Extension Ecosystem Summit took place at PGConf.dev in Vancouver on May 28, 2024 and it was great!

Florian Nadler: From Microsoft SQL server to PostGIS

18. Juni 2024 - 7:26

PostGIS is getting more and more popular and for good reasons. It benefits from a great community and offers a huge set of cool and stable features. Nowadays, a lot of customers want to migrate their spatial datasets from various data sources to PostGIS, where they can easily work with them.
Today I want to take a closer look at how this migration could look like for those transitioning from Microsoft SQL server to PostGIS.  

My article is structured as follows:

Suman Michael: Extending PostgreSQL with Rust and OpenAI Integration

17. Juni 2024 - 15:23

PostgreSQL is a powerful and versatile database management system. One of its strengths lies in its extensibility. In this blog, we will explore how to extend PostgreSQL using Rust, specifically focusing on creating a custom extension called pg_summarize that integrates with the OpenAI API. This extension will include a basic "Hello, pg_summarize!" function and another […]

Robins Tharakan: Compiling latest gcc to test more architectures

15. Juni 2024 - 22:38
Off late, I've had two separate needs to compile GCC by hand and although my first foray into compiling gcc from git took patience, stumbling over the basics was interesting to say the least.The first time I realised that an old GCC version could matter, was this feedback [1] that one of my buildfarm members was running an old (for its arch) gcc version, something that I almost never paid much

Christoph Schiessl: Force Index Usage by Manipulating the Query Planner

15. Juni 2024 - 2:00
Learn how to manipulate PostgreSQL's query planner to force it to use your indexes while working on optimizing the performance of your queries.

Radim Marek: The time keepers: pg_cron and pg_timetable

15. Juni 2024 - 2:00

Working with PostgreSQL, and virtually any database system, extends far beyond merely inserting and retrieving data. Many application and business processes, maintenance tasks, reporting, and orchestration tasks require the integration of a job scheduler. While third-party tools can drive automation, you can also automate the execution of predefined tasks directly within the database environment. Although system-level cron might be a starting point, the power of the database system lies in its ability to store all the necessary information alongside your data/schema.
