> semi related to this, I have always thought that the way postgresql
handles the deletion of users and groups to be flawed.  If I create a user,
grant permissions on a table and then drop the user, permissions now exist
on that table for a user that does not exist.  I see this as a possible
security flaw since a new user can then be created with the user id of the
ID user and have all the permissions that might have ever been assigned to
that old user.  When a user is deleted, shouldn't all permissions associated
with that user be deleted also, I would think this could be handled with a
PK/ FK cascading delete type setup.
