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.
As we will be using a foreign server and a user mapping in this recipe, please follow all the previous recipes before proceeding.
For this recipe, we will perform all actions on the pg-report
PostgreSQL server in the pgbench
database. Follow these steps to create a table in pg-report
, which refers to a table on pg-primary
within pgbench
