PGConf.Russia 2021

JSON is now the de facto standard for startup developers. Why is this happening and what should be done? Should we teach application developers how to properly design a database according to the canons of relational theory (which Postgres complies very well with) or make the DBMS more JSON-friendly?

PostgreSQL could easily be named the master of indexes - there is no other database that could compete with Postgres for the variety of indexes. How developers can use this advantage effectively in their day to day work? How do you know which index to create? When the created index might slow our application’s performance? We will try to get our head around this topic with some use cases and live examples. This talk would be of interest for any developer who wants to expand their knowledge of indexes in Postgres and secure the best performance for their application.

Optimisation of queries can have a significant impact on database performance. In my talk, I will review the tools that we use in our practice and discuss some use-cases. This talk is of interest to database administrators or developers who would like to optimise their database performance and learn new query optimisation techniques.

This talk is about postgres extension pg_profile - simple historic database workload profiler. I'll talk about its new features and new statistics available in Postgres 14. There is a branch of pg_profile named pgpro_pwr, designed to run in PostgresPro Enterprise Edition and PostgresPro Standard Edition databases. It is using extended performance statistics of those databases providing some valuable benefits. We'll see what's new in pgpro_pwr extension. Also I'll talk about some problems in postgres performance monitoring and their possible solutions in the future.
