## 52.49. pg_replication_origin

The pg_replication_origin catalog contains all replication origins created. For more on replication origins see [Chapter 48](replication-origins.md). 

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. 

**pg_replication_origin Columns**

| Column Type | Description | 
| --- | --- |
| `roident` `oid` | A unique, cluster-wide identifier for the replication origin. Should never leave the system. |
| `roname` `text` | The external, user defined, name of a replication origin. |
