"By default, all tables and views existing in a particular schema on the
foreign server are imported"
The emp table did not exist when you did the initial IMPORT FOREIGN
SCHEMA. You will need to import it using either CREATE FOREIGN TABLE or
IMPORT FOREIGN SCHEMA. NOTE: For IMPORT FOREIGN SCHEMA you can exclude
the existing table using:
EXCEPT ( table_name [, ...] )
