my point was that '\x65' as a literal
is read as 'e', but '\\x' || '65' is
just the concatation of 2 2-char varchars

you might be able to do what you want with
set_byte() and encode().
CREATE OR REPLACE FUNCTION myfunction()
RETURNS varchar AS
$x$
DECLARE x bytea := ' ';
BEGIN
FOR i in 101..105 LOOP
x:=set_byte(x,i-101,i);
END LOOP;
RETURN encode(x,''escape'');
END;
$x$
LANGUAGE 'plpgsql';
select myfunction();
