## 52.25. `pg_foreign_table`
[]()
The catalog `pg_foreign_table` contains auxiliary information about foreign tables. A foreign table is primarily represented by a [`pg_class`](catalog-pg-class.html) entry, just like a regular table. Its `pg_foreign_table` entry contains the information that is pertinent only to foreign tables and not any other kind of relation.
