[2/4] sepostgresql-sepgsql-8.4devel-3-r739.patch
      provides SE-PostgreSQL feature, based on PGACE framework.
  
http://sepgsql.googlecode.com/files/sepostgresql-sepgsql-8.4devel-3-r739.patch

[3/4] sepostgresql-pg_dump-8.4devel-3-r739.patch
      enables to dump databases with security attribute.
  
http://sepgsql.googlecode.com/files/sepostgresql-pg_dump-8.4devel-3-r739.patch

[4/4] sepostgresql-policy-8.4devel-3-r739.patch
      provides the default security policy of SE-PostgreSQL.
