PostgreSQL 19's release cycle has encountered unprecedented instability, with eight major features committed in the final five weeks before feature freeze, leading to multiple reversions since August due to design issues and unexpected coupling with other subsystems. As of mid-September 2026, the project aims for GA by end of October despite ongoing disputes over remaining features like REPACK, online checksums, and FOR PORTION OF.
A 2018 physics paper argues that the Fermi paradox—the puzzle of why we observe no intelligent alien life despite mathematical models suggesting it should be common—dissolves when accounting for realistic uncertainties in parameters like the Drake equation. The authors show that when uncertainty distributions are properly modeled rather than assumed certain, there is substantial probability of no other intelligent life in the observable universe, eliminating the paradox.
