I don't understand -- why wouldn't we just have two columns, one for
plain row-level security and another for whatever security system the
platforms happens to offer? If we were to follow that route, we could
have row-level security first, extracting the feature from the current
patch; and the rest of PGACE could be a much smaller patch implementing
the rest of the stuff, with SELinux support for now with an eye to
implementing Solaris TX or whatever.
