When version 16 comes in it´ll be possible to define [1] field STORAGE on
CREATE TABLE step.
I have some thousands of toast files which are completely useless on my

pg_upgrade ? Those unneeded toast files will be dropped automatically ?
If not, if I do "alter table x alter column y set storage main" then toast
file will still exist ?
