Speaker Interview with Hervé Schweitzer

Could you briefly introduce yourself?
I am the Chief technical officer (CTO) of dbi services. I have a 20-year technical background in the Oracle Database field. I’ve started with PostgreSQL database in 2017, and since 2019 I’ve also been in charge of the dbi Insite PostgreSQL DBA Essential and PostgreSQL Tuning workshops. In addition to my experience with Oracle and PostgreSQL, I’m also helping our customers to transfer their database workloads to different Cloud providers such as Oracle Cloud and AWS Cloud.
How do you engage with the PostgreSQL Community?
I am the referent for the PostgreSQL DBA and Tuning workshops that are both based on the community version. Besides that, I am keen on testing new tuning functionalities and on providing the community with my feedbacks.
Have you enjoyed previous pgconf.eu or FOSDEM conferences, either as an attendee or as speaker?
Yes, I have. I enjoyed my first participation as an attendee at the pgconf.eu in Lisbon. There, I had the opportunity to meet several developers of the community who were open to share their knowledge and who also relayed my blog posts about my tests on their developments.
What will your talk be about, exactly? Why this topic?
Today, we have numerous customers who used to work only with Oracle databases but now also need to manage PostgreSQL databases. In my session, I will address the Tuning part of these two RDBMS in which many elements are similar and some are obviously different. The most important message in this session is that each RDBMS can learn from the other :-). This session doesn’t require any Oracle database knowledge and you will discover what PostgreSQL can learn from Oracle.
What is the audience for your talk?
I’ve already presented this session seven times in three different languages this year. Whatever the audience, the attendees appreciated this session as it is an introduction to the world of Performance Tuning.
What existing knowledge should the attendee have?
There is no need for any technical knowledge to attend my session. I’ve presented it to sales people without tech skills a couple of times. Not only did they like it, but they also understood it.
What is the one feature in PostgreSQL 12 which you like most?
Pluggable storage, even if invisible to the end user.
Which other talk at this year's conference would you like to see?
Every session about PostgreSQL optimization :-).
Which measure, action, feature or activity would—in your eyes—help to accelerate the adoption of PostgreSQL?
Keep up the good work and continue as it is!
