A new command in the pgenv script.

pgenv gains a new command (and contributor!)

[pgenv](https://github.com/theory/pgenv){:target="_blank"} , the PostgreSQL binary manager written as a Bourne Again Shell script, has gained a new command: status.

Once again, Postgres has been elected DBMS of the Year by DB-Engines. Although this is only a ranking, it gives a trend. It has also been recognized for several years in Stackoverflow surveys : Most popular Databases.

Three weeks ago, we wrote a blog comparing pg_vector and lantern on index creation and search speed, and also mentioned that this is a fast evolving space with great momentum.

Just last week, we saw the release of Pgvector v0.6.0, which contains improvements in HWSW build time thanks to the ability to build indexes in parallel.

A way to fix some oddity that comes from other databases.

Changing a Column from Integer to Boolean in One Transaction

I was migrating a database from SQLite3 to PostgreSQL, not because the former isn’t good, rather because the latter shines!

The presentation I gave for Chicago PUG in January was a reserved talk for FOSDEM, so I hold of with sharing until after the conference. Now that the conference is over, here is it!

This month’s PGSQL Phriday #015 topic is about UUIDs, hosted by Lætitia Avrot. Lætitia has called for a debate. No, no, no. I say let’s have an all-out war. A benchmark war.

I have decided to orchestrate a benchmark war between four different methods of storing a primary key:

I went to work on a brilliant new idea for a FreshPorts feature and I immediately hit a snag on my dev system. I noticed that the package importing system had not run anything recently. The reason why was in the logs: In this post: FreeBSD 14.0 PostgresQL 16.1 py39-psycopg2-2.9.9 Python 3.9.18 First, why did […]

This month’s PGSQLPhriday event is about UUId thanks to my post calling for a fight debate on the topic. I will answer a question a friend developer asked me: “What is the best when we need a primary key? UUID, CUID, or TSID?” TL;DR: please don’t The answer is: “It depends!” Yes, it’s a running joke amongst consultants: you can always answer all customers' questions with an “it depends”. The reason for that is simple: if the answer was obvious, you wouldn’t need the consultant!

This month, we have an invitation from Lætitia to talk about UUIDs. UUIDs are a hot topic, and Cybertec wrote several posts earlier.

You have a JSON dataset that you want to upload to a PostgreSQL table containing properly formatted rows and columns... How do you do it?

All the main sources like my own blog and others tell you to load the JSON in a dedicated temporary table containing a unique JSON column, then parse it and load into the target table. However there could be another way, avoiding the temp table!

Welcome back to the second article in our series exploring PostgreSQL cursors. In the first part of this series, we explored the fundamentals of scrollable cursors. In this article, we’ll shift our focus to non-scrollable cursors and explore how they can enhance your data navigation experience with PostgreSQL Cursors. Understanding Non-Scrollable Cursors Non-scrollable cursors in […]

TL;DR

As I think through the future of the Postgres extension ecosystem as a key part of the new job, I wanted to understand how Go decentralized publishing works. In this post I work it out, and think through how we might do something similar for Postgres extension publishing.

Over on the PGXN Blog I’ve posted a brief update on recent bug fixes and improvements to the pgxn-tools Docker image, which is used fairly widely these days to test, bundle, and release Postgres extensions to PGXN. This fix is especially important for Git repositories:

Just a quick note to highlight some bug fixes and improvements in the pgxn/pgxn-tools Docker image in the last few weeks.

I recently found about the StackOverflow dataset in Kaggle, which points to the StackExchange link to download the entire data. In this blog I'll show a (maybe not 100% polished) way to upload the data to several tables in a PostgreSQL database!

This month's PgSQLPhriday #015 topic is about UUIDs. Lætitia Avrot is this month's host, see her post for the full challenge text. The topic is described as a debate between the Database People and Developers. I'm not sure there's such a clean divide on people's opinions on the topic, as I know plenty of Database People that have settled on using UUIDs as their default. Similarly, I know even more developer types that have followed the arguably more conventional choice of using an auto-incrementing ID.

At PostGIS Day 2023, one of our speakers showed off a really cool demo for getting JSON and SVGs in and out of Postgres / PostGIS and into Google Sheets. Brian Timoney put together several open source projects in such a cool way that I just had to try it myself. If you want to see his demo video, it is on YouTube.

Last week, I informally shared Extension Ecosystem: Jobs and Tools with colleagues in the #extensions channel on the Postgres Slack.

As in previous years, I've pulled together a few statistics on code contributions to PostgreSQL. See previous posts in this series for methodology and caveats. I calculate that, in 2023, there were 221 people who were the principal author of at least one PostgreSQL commit. 66% of the new lines of code were contributed by one of 18 people, and 90% of the new lines of code were contributed by one of 50 people. Here they are. Asterisks indicate non-committers.
