pg_shseclabel
   The catalog pg_shseclabel stores security
   labels on shared database objects.  Security labels can be manipulated
   with the SECURITY LABEL command.  For an easier
   way to view security labels, see Section 52.84.
  
   See also pg_seclabel,
   which performs a similar function for security labels involving objects
   within a single database.
  
   Unlike most system catalogs, pg_shseclabel
   is shared across all databases of a cluster: there is only one
   copy of pg_shseclabel per cluster, not
   one per database.
