Applied with really pretty minor revisions --- this was a nice clean
patch. Changes I can recall making:

* You missed one or two documentation references to DELETE privilege.

* You modified the privileges test to create another userid, but forgot
to clean up afterwards.

* LOCK TABLE requires UPDATE or DELETE privilege for locks stronger
than AccessShareLock. I thought it would be inconsistent to not allow
TRUNCATE to satisfy this requirement too.

* Many of the information_schema views require some privilege on a table
to show details about the table. Again, it seemed inconsistent to not
allow TRUNCATE privilege to satisfy this requirement.

* A couple of the information_schema views show available privileges on
tables by name. It's a bit dubious whether we should show TRUNCATE in
them, since there is no such privilege bit in the SQL standard, but
after some reflection I concluded that functionality trumps a narrow
reading of the spec here. We can revisit that if anyone wants to argue
for the other way, though.
