Creating a foreign table

The last step in initializing foreign data access is the creation of the foreign table itself. While doing so, we are limited to specifying column names, types, default values, and whether or not each column is nullable. This table skeleton helps the PostgreSQL query planner interact with the remote data as efficiently as possible.

In this recipe, we will create a foreign table and make it ready for use by our mapped user.

Getting ready

As we will be using a foreign server and a user mapping in this recipe, please follow all the previous recipes before proceeding.
