You can store all values in an array.

Something like:

.... 
declare
   l_names text[];
begin
   ...
   select array_agg(name) 
       into l_names
   from cloud_table;

   -- pass the array to a function
   perform some_function(l_names);

   ...
end;

If you already have a function that accepts an array as a parameter and you want to pass the result of your select as an array, you can use:

select your_function(array(select name from cloud_table));
