Permissions problem

Hi,

There seems to be a minor bug related to permissions.  If you create a
table and grant permissions on that table to someone else, you lose your
own permissions (note: do this as a non-dbadmin account):

  testdb=> create table tester ( test int4 );
  CREATE  
  testdb=> insert into tester values ('1');
  INSERT 17109139 1
  testdb=> grant select on tester to someone;
  CHANGE
  testdb=> insert into tester values ('2');
  ERROR:  tester: Permission denied.
  testdb=>

>From postgres/sql-grant.htm:

 Description
   
   GRANT allows the creator of an object to give specific permissions to
   all users (PUBLIC) or to a certain user or group. Users other than
   the creator don't have any access permission unless the creator
   GRANTs permissions, after the object is created.
   
   Once a user has a privilege on an object, he is enabled to exercise
   that privilege.  There is no need to GRANT privileges to the creator
   of an object, the creator automatically holds ALL privileges, and can
   also drop the object.  

It's not behaving as documented ("There is no need to GRANT privileges
to the creator of an object").

This is in postgresql-7.0.3, but it's possible this is fixed in a more
recent version - can someone try this and see what happens ?

Cheers,

Chris.
