Python may not be the fastest programming language on the CPU, but its fast and easy development saves a lot of costs between the keyboard and the chair. Since database clients spend most of their time waiting for a response from the database server, Python's asynchronous functionality available in the recent versions (3.5+) may help to optimize the application's runtime considerably by working on something else while server's response is being prepared. The asynchronous interface between Python and PostgreSQL is called "asyncpg". In the workshop we'll explore this library and write a short application using some of its useful features.

Stop paying for Larry’s boat!

PostgreSQL is a fully-featured, enterprise-grade and open source database, named two years in a row database of the year! And it’s also the best candidate to migrate off of Oracle, supporting very advanced SQL, easy administration and pl/pgsql, a replacement for Oracle’s PL/SQL. Stop spending hundreds of thousands or millions of $ on database licenses and reinvest them in your team, infrastructure and software.

Join this half-day tutorial to learn the best practices, tricks and tools to perform a successful Oracle to PostgreSQL migration. Learn from the team that performed 150M users Blackberry migration to PostgreSQL on GCP with near-zero downtime, and the key author behind orafce, a set of Oracle compatible functions on top of PostgreSQL.

My presentation is about writing extensions in Postgres. I have written pg_threads that implements simplified POSIX thread API inside Postgres database. It adds a new powerful abstraction giving database developers new opportunities for writing parallel code thus taking advantage of multicore CPUs. There is an extra API for transactional and non-transactional IPC between threads. I also have an example application that takes advantage of this new API that scales linearly even across 2 nodes. The presentation is with live working demo using vagrant project with 2 VMs running Ubuntu and 2 Postgres 11 databases.

PostgreSQL 12 Feature Freeze is scheduled for April 2019, which didn't come yet. But general shapes of upcoming release are already visible. In this talk I'll consider patches already committed to PostgreSQL 12 as well as patches, which would be committed very likely. I'll talk with special passion about SQL/JSON, Merge, pluggable table access methods and zheap.
