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
