I waited for a couple of days to start my PG Day Chicago marketing campaign, and I hope that by now, everybody is more or less back to office/back to work/back to reality. Right? So, here is my list of aska:
Five days before Christmas I committed my patch to add incremental backup to PostgreSQL. Actually, I've been committing preparatory patches for some months now, but December 20 saw the two main patches land. Since then, there's been a bunch of bug-fix commits, and there are still a few pending items that need to be addressed, but the core of the feature is now committed. If you want a quick overview of the feature, Lukas Fittl has a great video about that.
For decades, PostgreSQL has reigned as the relational database champion, meticulously organizing data into rows and columns. But the information age craves more than just order; it demands understanding. Enter pgvector, a revolutionary extension that infuses PostgreSQL with the magic of vector data. Imagine text, images, or even sounds transformed into multi-dimensional points in space, […]
I have started using clangd (with a “d”) for PostgreSQL development. Maybe you want to try it too.Introduction
What is clangd? To quote directly from the web site:
clangd understands your C++ code and adds smart features to your editor: code completion, compile errors, go-to-definition and more.
clangd is a language server that can work with many editors via a plugin.
(They talk about C++, but this applies to C equally.)
PostgreSQL’s powerful full text search feature supports several query syntaxes. Of these, a website search feature should typically pick the websearch syntax. websearch copies some features from popular search engines, as covered below, offering familiar short syntax to users. It is also forgiving and will never raise a syntax error for user input, whilst other syntaxes can.
If you’ve ever dug under the hood of Postgres a bit, you’ve probably heard about the page. This is the on-disk storage mechanism and it's limited to an 8kb size. But what happens when you have data bigger than that 8kb? TOAST is made. Postgres TOASTs data by splitting it up into smaller chunks. TOAST stands for The Oversized Attribute Storage Technique.
TOAST happens automatically, you don’t set up anything, it just comes with Postgres out of the box. So why should you care?
A question I often hear, and also ask myself, is “where is PostgreSQL going?” This is a deep question: it’s not limited to the work on the core database engine, but rather everything going on in the community, including related open source projects and event and community development. Even with the popularity of PostgreSQL, which was selected as DB Engine’s “DBMS of the Year” for the fourth time, it’s a good idea to step back at times and reflect on what PostgreSQL will look like in the future.
- rewriting dbms_pipe and dbms_alert in orafce. Now the conditions variables are used (for synchronization) instead timeouts, and the lags in the communication are significantly reduced,
- fix pspg and PDCursesMod so pspg can be used with other curses than ncurses. Originally pdcurses didn't support stream redirection. Still only VT environment is supported (far target is support pspg on new Microsoft Windows terminal),
- Rewriting background of profiler, tracer routines in plpgsql_check.

Yet another disadvantage of a conference happening in December: first, you do not have time to blog about it, and then, nobody has time to read your posts because everybody is busy celebrating all possible holidays!

Because Who Needs Another Gold Statue Anyway?
In the world of databases, where seriousness often reigns supreme… Well, you know me! I always want to inject a bit of humor and fun. Welcome to the inaugural “Golden Trunk 2023” award – my impulsive celebration of PostgreSQL community brilliance, where a golden elephant trunk steals the spotlight. Inspired by the grandeur of events like the Oscars and Globes, the “Golden Trunk” award was born – a celebration of the best articles about PostgreSQL!

This year, the 13th annual PostgreSQL Conference Europe (PGConf.EU for short) took place from December 12th to December 15th in the beautiful Central European city of Prague.
Before the main conference begins, there is a full day of training delivered by expert PostgreSQL professionals from all over the industry.
