Heikki Linnakangas: Multi-threaded PostgreSQL? (PGConf.EU 2023)

I started a thread on pgsql-hackers "Let's make PostgreSQL multi-threaded" in June. That spurred a lot of discussion, which even made it to LWN and hacker news. There is little code to show, but I will paint a picture of what it would look like: - Multithreading vs multi-process architectures in general - Pros and cons - How exactly multiple threads could be used - Hybrid approaches - Previous attempts - How other large projects have made the switch - How PostgreSQL can make the switch
