IMPORT_FOREIGN_SCHEMA - import table definitions from a foreign server

The IMPORTFOREIGNSCHEMA command conforms to the SQL standard, except that the OPTIONS clause is a PostgreSQL extension.

IMPORTFOREIGNSCHEMA creates foreign tables that represent tables existing on a foreign server. The new foreign tables will be owned by the user issuing the command and are created with the correct column definitions and options to match the remote tables. By default, all tables and views existing in a particular schema on the foreign server are imported. Optionally, the list of tables can be limited to a specified subset, or specific tables can be excluded. The new foreign tables are all created in the target schema, which must already exist. To use IMPORTFOREIGNSCHEMA, the user must have USAGE privilege on the foreign server, as well as CREATE privilege on the target schema.
