September 25th marks the release of PostgreSQL 18. This article covers the March CommitFest and concludes the series covering the new features of the upcoming update. This article turned out quite large, as the last March CommitFest is traditionally the biggest and richest in new features.

You can find previous reviews of PostgreSQL 18 CommitFests here: 2024-07, 2024-09, 2024-11, 2025-01.

Global indexes for partitions in Postgres Pro: uniqueness without hacks

Level of difficultyMedium
Reading time5 min
Views346

When there’s no filter on the partitioning key, local indexes turn into a marathon across partitions. The new gbtree keeps a single catalog of keys and jumps straight to the row by primary key. In this article, we’ll show the algorithm, real numbers and limitations (primary key is mandatory, ON CONFLICT does not work) — and where this eases the pain in CRM/billing.

Новая атака с использованием бэкдора PhantomRShell

Level of difficultyMedium

В августе, благодаря нашей песочнице, была предотвращена атака на российские организации с применением нового вредоносного кода. Изначально мы предположили, что это массовый фишинг с серверов злоумышленников, который каждый день можно встретить на почте любой организации. Но оказалось, что отправитель письма вполне легитимный: он был скомпрометирован злоумышленниками, нацеленными на российские оборонные и промышленные организации.

Хакеры использовали сложную схему сокрытия вредоносной нагрузки в архивах-полиглотах. Полиглоты — это файлы, которые могут быть валидны с точки зрения спецификации нескольких форматов. Сама вредоносная нагрузка является новой обфусцированной вариацией инструмента PhantomRShell, который использует группировка PhantomCore (ранее мы писали про нее в блоге).

В этой статье мы расскажем подробности атаки, ее возможный исходный вектор и дадим рекомендации по защите почтовой инфраструктуры от взлома и подобных атак. Интересно? Добро пожаловать под кат!

Postgres Pro TDE — security and performance

Level of difficultyMedium
Reading time14 min

TDE comes in many flavors — from encryption at the TAM level to full-cluster encryption and tablespace markers. We take a close look at Percona, Cybertec/EDB, Pangolin/Fujitsu, and show where you lose performance and reliability, and where you gain flexibility.

On top of that, Vasily Bernstein, Deputy head of product development, and Vladimir Abramov, senior security engineer, will share how Postgres Pro Enterprise implements key rotation without rewriting entire tables — and why AES-GCM was the clear choice.

The Russian trace in the history of the PostgreSQL logo

The story of the PostgreSQL logo was shared by Oleg Bartunov, CEO of Postgres Professional, who personally witnessed these events and preserved an archive of correspondence and visual design development for the database system.

Our iconic PostgreSQL logo — our beloved “Slonik” — has come a long way. Soon, it will turn thirty! Over the years, its story has gathered plenty of myths and speculation. As a veteran of the community, I decided it’s time to set the record straight, relying on the memories of those who were there. Who actually came up with it? Why an elephant? How did it end up in a diamond, and how did the Russian word “slonik” become a part of the global IT vocabulary?

Build a Short Video App Like DramaBox to Engage Global Audiences

Level of difficultyEasy

Short video apps have completely reshaped how people consume entertainment. Instead of sitting down for a two-hour movie or a 45-minute TV episode, viewers are now hooked on bite-sized videos that fit into their busy schedules. This shift has been accelerated by Gen Z and Millennials, who prefer quick storytelling formats that are both interactive and engaging.

In 2025, the OTT and short video industry is projected to see over 1.5 billion monthly active users worldwide, with an average revenue per user (ARPU) of nearly $12. The reasons are clear: affordability, accessibility, and convenience. The success of apps like DramaBox shows that people are willing to spend money on shorter dramas as long as they deliver strong storytelling.

For entrepreneurs, this presents a golden opportunity to build OTT platforms like DramaBox and tap into this global demand.

Building a Resume Matcher with tRPC, NLP, and Vertex AI

I share how I built a resume matcher app using tRPC, TypeScript, and Google Vertex AI. The project takes PDF resumes and job postings, extracts text, applies basic NLP for skill detection, and then calls Gemini 1.5 Flash for deeper analysis. Along the way, I explain why tRPC felt faster and cleaner than REST or GraphQL for an MVP, show code snippets from the repo, and discuss both the benefits and trade-offs of this approach.

How we loaded a petabyte into PostgreSQL before New Year — and what happened next

Level of difficultyMedium

It all started as a joke by the office coffee machine. But, as with every decent joke, it suddenly sounded worth trying — and before we knew it, we were knee-deep in an experiment that turned out to be anything but trivial, complete with a whole minefield of gotchas.

It began simply: while everyone else was busy debating hardware tuning and squeezing out extra TPS from their systems, we thought — why not just shove a huge chunk of data into PostgreSQL and see how it holds up? Like, really huge. Say, a one-petabyte database. Let’s see how it survives that.

It was December 10, the boss wanted the report by January 20, and New Year was less than a month away. And that itch that all engineers know? It hit hard.

How to load test PostgreSQL database and not miss anything

Level of difficultyMedium
Reading time14 min
Views891

During load testing of Tantor Postgres databases or other PostgreSQL-based databases using the standard tool pgbench, specialists often encounter non-representative results and the need for repeated tests due to the fact that details of the environment (such as DBMS configuration, server characteristics, PostgreSQL versions) are not recorded. In this article we are going to review author's pg_perfbench, which is designed to address this issue. It ensures that scenarios are repeatable, prevents the loss of important data, and streamlines result comparison by registering all parameters in a single template. It also automatically launches pgbench with TPC-B load generation, collects all metadata on the testing environment, and generates a structured report.

41 TB/day from Oracle to Postgres Pro without stopping the source system — not theory, but numbers from our latest tests. We broke the migration into three stages: fast initial load, CDC from redo logs, and validation, and wrapped them into ProGate. In this article, we’ll explain how the pipeline works, why we chose Go, and where the bottlenecks hide.
