The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/16/sql-move.html
Description:
A few more examples with the other options would be helpful.
MOVE LAST for example shows NULL,
What does MOVE ALL do?

I found out demo in
https://git.postgresql.org/cgit/postgresql.git/tree/src/test/regress/expected/subselect.out#n1665
You can try it:
begin;
declare c1 scroll cursor for
select * from generate_series(1,4) i
where i <> all (values (2),(3));
move forward all in c1;
fetch all in c1;
commit;
move the default direction is forward. so "move all" will act the same
as "move forward all".
