CREATE STATISTICS - what is it for?

Date: 2018-10-25
Time: 10:30–11:20
Room: New York
Level: Intermediate

In this talk I'll explain why we need this capability at all, how it works, which cases it already helps with, and what improvements are in the queue for future PostgreSQL versions.


The following slides have been made available for this session:
