What plan do you have for system columns added by the patch
(datsecon, nspsecon, relsecon, etc) after we have securty_id
system column? Will we have duplicated features then?
Even if system tables don't use security_id columns, should the data type
of *secon be oid instead of text? I think pg_security described in the wiki
page is useful even if we only have object-level security.
How about adding pg_security and changing the type of *secon to oid?
