Patch by kaigai on 2011-06-09 08:15:07 AM: Initial version.
Patch by kaigai on 2011-06-28 08:37:26 AM: Splitted into two patches:
1) syscache on pg_seclabel
2) userspace access vector itself

Also, message includes performance measurement.
Patch by kaigai on 2011-07-02 10:02:04 AM: pg_seclabel.provider was re-defined as NameData, instead of Text.
(To keep consistent with security label on shared object patch)
Patch by kaigai on 2011-07-14 07:47:55 PM: The latest version (v4)
Review by yhavinga on 2011-07-20 01:56:09 PM: Some minor remarks, nothing serious, great improvement in performance.
Review by rhaas on 2011-07-20 02:55:45 PM: Syscache memory usage and initialization cost seem problematic; still need to review UAVC portion of patch.
