51.53. `pg_subscription`

The catalog pg_subscription contains all existing logical replication subscriptions. For more information about logical replication see Chapter 30.

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.
