First, make sure that you're passing in an argument:
SELECT zufall(5);

When I try it on my test db (7.4) I get:
  testdb=# SELECT zufall(5);
  ERROR:  function chr(double precision) does not exist
  HINT:  No function matches the given name and argument types. You may
need to add explicit type casts.
  CONTEXT:  PL/pgSQL function "zufall" line 11 at select into variables
so you should also check the arguments and return type of the chr()
function.

Hope that helps.
