Beyond Joins and Indexes
Thursday, January 12, 2023
My presentation Explaining the Postgres Query Optimizer covers the details of query optimization, optimizer statistics, joins, and indexes. I have delivered it 20 times since 2011.
While that talk covers common optimizer issues, in recent years I began to feel it would be helpful to produce a comprehensive talk about the other plans the optimizer can choose. Researching all the details proved to be a challenge, and the result is Beyond Joins and Indexes, which covers the 42 other plans that were not covered in my previous optimizer talk. I delivered this talk at the DC PostgreSQL Users Group on Monday so I have now added the slides to my website.
