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.
