bug

Hello!

I'm sorry for my bad English.

I found a bug with user rights.

Situation:

CREATE TABLE kaka;
CREATE USER baka;
GRANT SELECT ON kaka TO baka;
SELECT relname, relacl FROM pg_class WHERE relname='kaka';

relname|relacl
-------+---------------
kaka   |{"=","baka=r"}

DROP USER baka;
SELECT relname, relacl FROM pg_class WHERE relname='kaka';

relname|relacl
-------+---------------
kaka   |{"=","33=r"}
              ^^^- Wow! Why?

CREATE USER abc;
SELECT relname, relacl FROM pg_class WHERE relname='kaka';

relname|relacl
-------+---------------
kaka   |{"=","abc=r"}

Wait, wait... I don't make access to user 'abc'.
User 'abc' got access to table kaka AUTOMATICALY!
