GRANT odd behaviour - Bug or feature?

Hi,
I discivered some strange behaviour in GRANT. When I
CREATE a table and GRANT some privilege to some user
this privilege is REVOKEd from me ?!? So I have to
GRANT the same to me afterwards. Once I have GRANTed
this privilege to myself I can GRANT it to whoever I
want without REVOKE-ing it from me. Really strange.
Here is some code for ilustration :

1) CREATE TABLE test(.......);
2) GRANT SELECT ON test TO user1;
3) SELECT * FROM test; -- permission denied.
4) INSERT INTO test values(.....); -- OK!
5) GRANT SELECT ON test TO myself;
6) SELECT * FROM test; -- OK!
7) GRANT SELECT ON test TO user2;
8) SELECT * FROM test; -- OK!

Is this a bug or feature :) ? I think this is a bug.

btw. there is one more strange thing i discovered with
inexes:
Asume we have a table with two indexes (index1 and
index2). When I cluster a table with index1 - index2
disappears and i have to create it again.
I know that there could be a reasonable explanation -
table reorder and etc... Is it normal?

regards,
Rumen
