Note that the above assumes you're using psql.
For tools other than psql, you'd have to use dynamic SQL something
like the DO block below. It will work on psql, just as well.
DO $$
declare
rec record;
begin
for rec in select
'alter user '|| quote_ident(usename)
||' with password '|| quote_literal('newpassword')
as c from pg_user
loop
raise notice 'Executing command: %', rec.c;
execute rec.c;
end loop;
end;
$$;
