  1. Proposal : changing table ownership

    Mark Hollomon <mhh@nortelnetworks.com> — 2000-09-08T13:26:12Z

    Syntax:

ALTER TABLE <table> OWNER TO <newowner>

Security:

The owner of a table will be able to change the owner to any other user.
The superuser will NOT have special privileges.

Doesn't this create risks parallel to file give-away (chown) in Unix?
A lot of Unices disallow chown except to the superuser.

Tables aren't currently active objects, but we've been talking about
things like making trigger functions run "setuid" to the table owner.
If that happens then table ownership giveaway is a big security hole.

Say *what* ?  That's just silly.

*Only* superuser should be able to run the above command ...
