Vacuuming Enhancements in PostgreSQL 18: Faster, Smarter, More Predictable | POSETTE 2026
PostgreSQL 18 ships major vacuum improvements: async I/O, dynamic autovacuum scaling, and dead-tuple caps.
“PostgreSQL 18 delivers the most significant collection of vacuum and analyze improvements over the years.”
A POSETTE 2026 talk details PostgreSQL 18's vacuuming enhancements, including asynchronous I/O for heap scans, dynamically scalable autovacuum workers, a hard cap on dead tuples, eager freezing, and better observability. It is a useful database engineering update but carries minimal AI industry signal.
