updating table with Postgresql Foreign data wrapper

Question

1. I created a foreign data wrapper table named t_user into mySchema.

   IMPORT FOREIGN SCHEMA public LIMIT TO (t_user)
      FROM SERVER myServer INTO mySchema;
   

2. The myServer side t_user added some column, but the foreign table didn't update accordingly.

3. I tried to delete the foreign table t_user, but it was used by my view and materialized view t_user, so the deletion failed.

Any ideas on how to update this table?

As you have seen, the foreign table definition does not change when the underlying table changes.

If all you did is add a column, you can use ALTER FOREIGN TABLE to add a corresponding column to the foreign table. That should work even if views depend on the foreign table.

For example, if the column is of type text, you can do:

ALTER FOREIGN TABLE t_user ADD COLUMN my_column text;
