Could you briefly introduce yourself?

Sure, I am a Postgres core team member and EDB employee. I have been working with Postgres for 21 years.

Have you enjoyed previous pgconf.eu or FOSDEM conferences, either as attendee or as speaker?

Yes, I have attended and spoken at many pgconf.eu conferences and enjoyed them all. They are also in different European city every year, which gives me a chance to visit many new cities. I have been to FOSDEM a few times too.

What will your talk be about, exactly? Why this topic?

My talk on Friday is "Unlocking the Postgres Lock Manager". This is a complex topic that confuses many people. The talk covers the many locking levels and how to control them.

What is the audience for your talk?

It is for people wanting to better understand how Postgres handles conflicting requests and how it uses locking to make sure queries run properly.

What existing knowledge should the attendee have?

Well, users should have some experience with performing concurrent workloads, or at least a desire to learn about them.
