ORM libraries are widely used in backend development – let's take this for granted. ORM libraries are improving, developers are learning from their own and others' mistakes, and many have learned to write code for ORM that generates quite optimal queries for typical operations. Yet, limited functionality of existing tools is another problem related to ORM. This is especially true for Postgres, which has a lot of operators and constructs (both in the core and in extensions) that go beyond the SQL standard.
With LinqToDb ORM library you can write extensions that implement any SQL operator or construct very easy, literally using just one line. Full-text search, KNN, CTE (including recursive ones), working with arrays and jsonb, array_agg and jsonb_object_agg, table functions and LATERAL JOIN - all this can be easily used in ORM, which I will demonstrate during this talk!

Every DBA has in one way or another experienced the situation when PostgreSQL tables and indexes grow significantly in size. While looking for the reason for such behavior, we often conclude that database objects have "bloated". In this talk, we'll discuss the reasons behind bloating, create a testing environment to define the best method to reduce bloating. We'll also compare several anti-bloating utilities and get familiar with one more tool that helps us to efficiently struggle against bloating. We expect this presentation to become helpful for PostgreSQL DBAs of any experience level.

Why would you need the domestic DBMS? 1. Because of law requirements: only domestic DBMSes are appropriate for data protection. 2. In terms of formalization: currently, it is impossible to purchase MS in Russia legally. 3. In terms of pricing: the licensing mechanism of foreign DBMS systems significantly increases the expenditures on protection. 4. In terms of performance: it depends on the optimization of information protection tools, which are currently developed for domestic DBMS systems (in order to reveal why you may refer to the first paragraph). 5. In terms of practice: by the end of last year we’ve finished transition to the domestic databases and everything works smoothly. What else does an information security officer need?
