First of all, let's make a distinction to prevent confusion:
The PostgreSQL Foreign Data Wrapper is a specific contrib extension that uses the Foreign Data Wrapper infrastructure to connect to remote PostgreSQL servers.

Foreign Data Wrapper extensions for other database systems will be discussed in the next recipe, Accessing objects in other foreign databases.
