pg_subscription   The catalog pg_subscription contains all existing
   logical replication subscriptions.  For more information about logical
   replication see Chapter 31.
  
   Unlike most system catalogs, pg_subscription is
   shared across all databases of a cluster: There is only one copy
   of pg_subscription per cluster, not one per
   database.
  
   Access to the column subconninfo is revoked from
   normal users, because it could contain plain-text passwords.
