Radim Marek: Custom PostgreSQL extensions with Rust

24. Mai 2024 - 2:00

This article explores the pgrx framework, which simplifies the creation of custom PostgreSQL extensions to bring more logic closer to your database. Traditionally, writing such extensions required familiarity with C and a deep understanding of PostgreSQL internals, which could be quite challenging. pgrx lowers the barrier and allows developers to use Rust, known for its safety and performance, making the process of creating efficient and safe database extensions much more accessible.

Elizabeth Garrett Christensen: Converting DMS to PostGIS Point Geometry

23. Mai 2024 - 19:00

I love taking random spatial data and turning it into maps. Any location data can be put into PostGIS in a matter of minutes. Often when I’m working with data that humans collected, like historic locations or things that have not yet traditionally been done with computational data, I’ll find traditional Degrees, Minutes, Seconds (DMS) data. To get this into PostGIS and QGIS, you’ll need to convert this data to a different system for decimal degrees. There’s probably proprietary tools that will do this for you, but we can easily write our own code to do it.

Deepak Mahto: Optimizing Performance in PostgreSQL: Join Column and ANY Filters

23. Mai 2024 - 9:54

Recently on the Postgres Slack, I encountered an interesting performance issue involving a SQL query that joins two tables with an ANY filter applied to one of the tables.

The problematic SQL was similar to the following:

SELECT tbl1.col1 FROM tbl1 INNER JOIN tbl2 ON tbl1.col1 = tbl2.col1 WHERE tbl2.col1 IN (1,2,3);

Table tbl1 is joined with tbl2 on the column col1 from their respective tables.

Henrietta Dombrovskaya: Carbon Footprint and Query Optimization

23. Mai 2024 - 5:20

I recently learned about this project, and I can’t stop thinking about it, and how it is strangely connected to what I was doing for a big portion of my professional life.

First of all, what is this project about? Since people rarely click the links, let me copy a project description here:

Jeremy Schneider: Default Sort Order in Db2, SQL Server, Oracle & Postgres 17

22. Mai 2024 - 19:28

TLDR: I was starting to think that the best choice of default DB collation (for sort order, comparison, etc) in Postgres might be ICU. But after spending some time reviewing the landscape, I now think that code-point order is the best default DB collation – mirroring Db2 and Oracle – and linguistic sorting can be used via SQL when it’s actually needed for the application logic. In existing versions of Postgres, this would be something like C or C.UTF-8 and Postgres 17 will add the builtin collation provider (more details at the bottom of this article).

Hubert 'depesz' Lubaczewski: Waiting for PostgreSQL 17 – MERGE / SPLIT partitions

22. Mai 2024 - 13:41
I thought about it for quite some time, whether I should write about it, and how. That's why there is delay since: On 6th of April 2024, Alexander Korotkov committed patch: Implement ALTER TABLE ... MERGE PARTITIONS ... command   This new DDL command merges several partitions into the one partition of the target table. … Continue reading "Waiting for PostgreSQL 17 – MERGE / SPLIT partitions"

Gabriele Bartolini: 16 Years After The Launch of 2ndQuadrant Italy: Remembering Simon Riggs

21. Mai 2024 - 15:18

Sixteen years ago, on May 21, 2008, we proudly announced the opening of the Italian branch of 2ndQuadrant, marking a milestone in PostgreSQL consulting and training in Europe. Simon Riggs, the visionary founder of 2ndQuadrant, placed immense trust in our small team from Prato, Tuscany. Tragically, Simon passed away on March 26, 2024, leaving a profound void. This article is my small tribute to Simon, his extraordinary leadership, and his invaluable contributions to the PostgreSQL community.

Peter Eisentraut: New compilers, new timings

21. Mai 2024 - 6:00

I had been eagerly awaiting the releases of Clang 18 and GCC 14 for the last few weeks. Now that they are both out, I figured I would check how fast they are for compiling PostgreSQL.

Samay Sharma: Introducing pg_timeseries: Open-source time-series extension for PostgreSQL

20. Mai 2024 - 11:00

We are excited to launch pg_timeseries: a PostgreSQL extension focused on creating a cohesive user experience around the creation, maintenance, and use of time-series tables. You can now use pg_timeseries to create time-series tables, configure the compression and retention of older data, monitor time-series partitions, and run complex time-series analytics functions with a user-friendly syntax.

Stefan Fercot: In-memory disk for PostgreSQL temporary files

20. Mai 2024 - 9:30

Recently, while debugging a performance issue of a CREATE INDEX operation, I was reminded that PostgreSQL might produce temporary files when executing a parallel query, including parallel index creation, because each worker process has its own memory and might need to use disk space for sorting or hash tables.

Radim Marek: Deep Dive into PostgREST - Time Off Manager (Part 2)

18. Mai 2024 - 2:00

Let's recap the first part of "Deep Dive into PostgREST," where we explored the basic functionality to expose and query any table using an API, demonstrated using cURL. All it took was to set up a db-schema and give the db-anon-role some permissions. But unless you are creating the simplest of CRUD applications, this only scratches the surface.
