“Andres Freund reviewed my patch and he looked at it and said, it seems to work really well, but I have no idea why.”
Postgres committers discuss the version 19 feature freeze, highlighting work on self-tuning asynchronous I/O worker pools and write-combining, plus the difficulty of heuristic-based features. The panel is about database engineering process and has little direct bearing on AI industry signals.
