PGConf.Siberia 2023

Unfortunately, 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.

PostgreSQL 16 is expected to be released in September. We are looking forward to a number of interesting and important changes in monitoring, logical replication and access management. My talk will cover these new features and many more; I am also open to conversations after the presentation.

Traditionally, fault tolerance in Postgres is achieved using built-in replication mechanisms and external utilities that monitor the state of running Postgres instances and react accordingly when various failures occur. In my presentation, I will tell you what we like and what we don’t like about this approach, what alternative we see, what we have been able to achieve to date and what we want to get by the release, which is planned for December.

We started using PLV8 in development in 2021. Primarily, we have started to build our Postgres + our own needs. However, after some time, we found an active growth in downloads. Over the past 10 months, our image has been downloaded over 100 thousand times, while we have not been engaged in its promotion. In this report, I will try to give an understanding of the growth in popularity of the project, briefly talk about its development, which improvements have aroused interest in the community, which have not, and share plans for the future.
