Artem Sergienko PostgresProHardening is the process of strengthening the security of a system in order to reduce risks from possible threats. In my presentation, I will tell you how to protect service cluster communications using TLS connections, in order to avoid accidental or unauthorized access to Patroni's REST API and ETCD storage.

Mikhail Zhilin PostgresProUnfortunately, ideal computer systems exist only in science fiction books. PostgreSQL is not exception and sometimes problems may occur. I would like to discuss how to correctly (and incorrectly) try to solve a problem, which way to choose, which tool to use.
The talk is of interest to both beginners and experienced users and database administrators.

Anton Doroshkevich InfoSoftBackup is still a stumbling block when migrating to PostgreSQL from other DBMSs. Its size directly depends on your experience and knowledge about the types of backups in PostgreSQL. In this talk, I will tell you about different types of backups, their pros and cons, and scenarios for using each type.

Nikolai Shaplov PostgresProFuzzing research is feeding random input data to a program (or a part of it) (in fact, randomness is very conditional) and seeing what we get out of it. And we repeat it many times on many processors.
Fuzzing a large monolithic program complex is never a simple task. It requires extraordinary solutions. In this talk, I will tell you what and how we searched with the help of fuzzing and what results it led to.
- Investigation of data type parsing functions (input-functions): for warming up;
- Investigation of functions implementing operations between types (op-functions): it is better to consider the structure here;
- Network subsystem fuzzing: let's pretend we are POSIX calls, it's cheaper that way;
- Recovering disk context: we need Groundhog Day.
A story about funny bugs and ridiculous hand gestures will be included.
