  The
  
   pg_replication_origin
  
  catalog contains
   all replication origins created.  For more on replication origins

  Unlike most system catalogs,
  
   pg_replication_origin
  
  is shared across all databases of a cluster: there is only one copy
   of
  
   pg_replication_origin
  
  per cluster, not one per
   database.
