| А deep dive into PostgreSQL query optimizations
During PostgreSQL maintenance, resource-consuming queries occur inevitably. Therefore, it's vital for every Database Engineer, DBA, or Software Developer to detect and fix them as soon as possible. In this article, we'll list various extensions and monitoring tools used to collect information about queries and display them in a human-readable way.
Then we will cover typical query writing mistakes and explain how to correct them. We will also consider cases where extended statistics are used for more accurate row count estimates. Finally, you will see an example of how PostgreSQL planner excludes redundant filter clauses during its work.

Multi-master cluster with sharding
Multi-master cluster with sharding which provides read/write scalability as well as high availability is obviously one of most wanted DBMS features. Experience shows that we should move in step-by-step manner in order to have it in core one day. Postgres Professional company joins community efforts in this direction.

Current approach for execution is essentially a kind plan tree interpretation. JIT-compilation of queries means compilation of plan tree into binary. Such compilation could get rid of multiple levels of indirection therefore accelerating queries.
