What's new in Postgres Professional training courses

Our company's educational projects are intended to facilitate learning of PostgreSQL. Last year, we focused on courses for application developers: we updated DEV1 basic course and released a brand new DEV2 course. What has changed in training materials representation, how we see the further development of the courses and what else do we have besides the courses, whether the courses for DBAs will be updated and how this will affect the certification and that's what I will talk about.

PostgreSQL Network Filter for EnvoyProxy

How do you monitor Postgres? What information can you get out of it, and to what degree does this information help to troubleshoot operational issues? What if you want/need to log all the queries? That may bring heavy trafficked databases down.

At OnGres we’re obsessed with improving PostgreSQL’s observability. So we worked together with Tetrate folks on an Envoy’s Network Filter extension for PostgreSQL, to provide and extend observability of the traffic inout a cluster infrastructure. This extension is public and open source. You can use it anywhere you use Envoy. It allows you to capture automated metrics and to debug network traffic. This talk will be a technical deep-dive into PostgreSQL’s protocol decoding, Envoy proxy filters and will cover all the capabilities of the tool and its usage and deployment in any environment.

High-Performance PostgreSQL

PostgreSQL is one of the leading open-source databases. Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. The default configuration is designed in such a way that PostgreSQL can run on any system using minimum resources. Consequently, a default installation of PostgreSQL does not give optimum performance on the high-performance machine because it is set up to use all available resources. PostgreSQL provides mechanisms that allow you to tune your database according to your workload and machine specification. Outside of PostgreSQL, though, we can tune the Linux kernel to allow the database load to work optimally. In this talk, we will learn how to tune some of the PostgreSQL’s parameters, and we will see the effect of that tuning, but we will focus on demonstrating how to tune Linux for better Postgres performance. As there are so many Linux kernel parameters that can be tuned to improve the performance of PostgreSQL, I will also share the results of benchmarks obtained when tuning some of the Linux parameters.

All about PostgreSQL Security

PostgreSQL provides different levels of security. This talk will cover all the available security techniques used in PostgreSQL 13. We’ll look at client-side security (LibPq, JDBC) through to server-side security. It will cover all supported authentication methods and the pros and cons of all these methods. Some of the key features of the talk are:

• Introduction to Cryptography
• SSL, TLS, GSSAPI, and OpenSSL
• Client-Side Encryption
• Securing Authentication
• Securing Data on the disk
• Securing Backup & Basebackup
• Securing Replication
• Database Roles and Privileges

It’s important to be familiar with all the security levels such as (1)network-level security (2) on-disk security (3) row-level, (4), and column level security. The talk will cover all the aspects with some real-life use cases and examples.
