That's even better -- I tried regproc, but forgot about regprocedure. I
think the problem will be, though, that the output of the reg* datatypes
is not castable to text, and therefore cannot be used to build a dynamic
sql statement.

select 'GRANT EXECUTE ON ' || 1142::regprocedure;
ERROR: array value must start with "{" or dimension information

But with the help of plpgsql:

create or replace function regprocedure2text(regprocedure)
returns text as '
begin
return $1;
end;
' language plpgsql;
CREATE FUNCTION
select 'GRANT EXECUTE ON ' || regprocedure2text(1142::regprocedure);
?column?
-----------------------------------------
GRANT EXECUTE ON date_mii(date,integer)
(1 row)
