Евгений Бредня PostgresProIn this talk, we will discuss what character encodings and collations are. I will explain the issues that can arise from sorting (COLLATION) in databases and show how these problems can be addressed using the COLLATION PROVIDER = ICU feature in PostgreSQL.

Дмитрий ДорофеевIn this talk, I will challenge architectural stereotypes about the impossibility of communication with external systems directly from a DBMS. PostgreSQL offers vast communication capabilities; you just need to know which extensions to use.
And when extensions aren't enough, you can create your own. For the Luxms BI project, we needed communication with NATS, so we developed our own extension in Rust. I’ll share the GitHub link and my experience of developing PostgreSQL extensions in Rust during this talk.

Константин Ратвин МФТИMany Russian companies are striving to establish themselves in the relational database market by developing their own commercial solutions, often based on forks of vanilla PostgreSQL. But beyond the database itself, customers also need a graphical management tool — Enterprise Manager. Since forking it is extremely challenging, vendors often have to build their own from scratch while considering competitive solutions.
This talk will explore Enterprise Managers from various Russian database vendors, comparing their key features — functionality, usability, and design — to identify which one stands out as the most effective.

Дмитрий Ремизов ГНИВЦThis talk explores the challenges we encountered — and solved — while migrating massive databases from Oracle to PostgreSQL.
One of the most complex aspects of this process was rebuilding foreign keys (FKs). To overcome these challenges, we had to dive deep into the internal workings of FK creation and validation.
Key topics include:
Does ALTER TABLE ... ADD CONSTRAINT ... FOREIGN KEY have an execution plan?
Can an ordinary user influence this process?
What locks are applied during FK creation and validation?
Also, we’ll introduce a first-principles method for investigating performance issues, applying it to a real-world FK creation bottleneck.
