permissions PB

Hi list,

The DB owner created a function as:
CREATE FUNCTION mysch.testaddint(int, int)
RETURNS int AS $$ SELECT $1+$2 $$LANGUAGE sql;

When usr1 is granted usage on domain mysch he can execute this function.
(which is strange as owner didn't grant execute on this fnct,
 I guess this is default behavior and thus ok.)

Until here, almost no PB, but after owner's:
REVOKE ALL ON FUNCTION mysch.testaddint(int, int) FROM usr1;

usr1 still can execute the function!? (#@<!>&)

Did I missed something somewhere?
