pg_replication_origin
The pg_replication_origin catalog contains all replication origins created. For more on replication origins see Chapter 48. 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.

| COLUMN | TYPE | DESCRIPTION |

roname |
textNOT NULL |
The external, user defined, name of a replication origin. |
Columns marked "implicit" are not included in SELECT *; some early statistics views are completed from same-version source, and the extra provenance is shown in the column description.
Common system columns 6
System attributes PostgreSQL provides, normally not expanded by SELECT *. Kept separately so they are not mixed in with ordinary columns.

|---|---|---|
tableoid | oid | -6 |
cmax | cid | -5 |
xmax | xid | -4 |

9.0 is the coverage baseline; a column already present in the baseline is not marked as added. The matrix aligns columns by name, so a rename appears as the old column removed and a new column added.
