51.36. pg_parameter_acl
  The catalog
  
   pg_parameter_acl
  
  records configuration
   parameters for which privileges have been granted to one or more roles.
   No entry is made for parameters that have default privileges.
 
  Unlike most system catalogs,
  
   pg_parameter_acl
  
  is shared across all databases of a cluster: there is only one
   copy of
  
   pg_parameter_acl
  
  per cluster, not
   one per database.
