## 52.42. `pg_replication_origin`

[]()

 The `pg_replication_origin` catalog contains all replication origins created. For more on replication origins see [Chapter 50](replication-origins.html).

 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.
