The built-in partitioning mechanism in PostgreSQL has been developing for several years. However, there is no magic button that would transform an ordinary table into a partitioned one. I will explain how to implement partitioning in a production system, how to prepare your table and apps for partitioning, and what pitfalls can make a DBA's life harder. We will also take a deep dive into various techniques of transferring data between partitions, also considering their pros, cons and limitation.

PostgreSQL protocol compression has been discussed in the community for a long time. Many different hypotheses have been expressed and tested, and the compression patch has received a large number of changes and improvements. I will review the various approaches tested during the implementation of protocol compression, and will highlight the current status.
