Many thanks for your efforts here. "Improve performance of internal row formation (David Rowley)" It's really deformation, not formation. As far as I know, nothing in v19 sped up tuple formation. I also think Nathan's work on autovacuum table prioritisation (d7965d65f) is worth a mention. There were concerns there that it might cause trouble for people who (for some reason) get best results from the previous pg_class-ordered priority. Having something in the notes about this might help direct someone towards why they're seeing autovacuum behave differently after upgrading. David
