A foreign server object represents a named external datasource, along with configuration information required to access the datasource. Server objects are referenced during foreign table creation to indicate the backing datasource. A foreign server object can be reused by multiple FOREIGN TABLES when the same external datasource is used. Three local file server objects, default_local_delimited
, default_local_parquet
, and default_local_regex_parsed
, are available for use directly in the CREATE FOREIGN TABLE statement when a custom server is not used.
