Draft of the SE-PostgreSQL documentation is here: http://wiki.postgresql.org/wiki/SEPostgreSQL

List of updates:
- The patches are rebased to the current CVS HEAD
- '--disable-row-acl' is removed. This feature is implicitly enabled when we don't activate any other enhanced security
features.From this change, SECURITY_SYSATTR_NAME got being always defined, so some of unnecessary #ifdef ... #endif
blockhas gone.
 
- bugfix: it caused a crash on COPY when we specify a system attribute on FORCE QUATE clause.
- cleanup: some warnings to notice unused variables are eliminated.
