The <code class="structname">pg_replication_origin</code> catalog contains
all replication origins created. For more on replication origins
see <a class="xref" href="replication-origins.html" title="Chapter 50. Replication Progress Tracking">Chapter 50</a>.

Unlike most system catalogs, <code class="structname">pg_replication_origin</code>
is shared across all databases of a cluster: there is only one copy
of <code class="structname">pg_replication_origin</code> per cluster, not one per
database.
