Can't you just include the "out" parameters in the result? 

    CREATE or replace FUNCTION public.test(x integer, y character varying(36))
      RETURNS TABLE  (id integer, filesize character varying(36), x integer, y varchar)
    AS $$
    begin
      x := 42;
      y := 'foo';
      
      RETURN QUERY
        SELECT t.*, x, y 
        FROM  public.tbl_employees t;
    END;

It's different because x and y are repeated for every row, but that's the only thing I can think of.

Can you show an example of a SQL Server procedure that demonstrates what 
you want to achieve?

I can't make sense of the below. I don't see where "x" and "y" are used 
in the function, unless they supposed to be "id" and "filesize". I have 
no idea what the QUERY is doing? Pretty sure you don't want an 
unconstrained select on a table. Can you provide a working example of 
what you are doing in SQL Server with sample output from same?
