This catalog exists in each coordinator and datanode in Postgres-XC as inheritted from PostgreSQL. Please note that current release of Postgres-XC does not support foreign data wrapper.
Note: The following description applies both to Postgres-XC and PostgreSQL if not described explicitly. You can read PostgreSQL as Postgres-XC except for version number, which is specific to each product.
The catalog pg_foreign_server stores foreign server definitions. A foreign server describes a source of external data, such as a remote server. Foreign servers are accessed via foreign-data wrappers.
