Getting ready

First of all, let's make a distinction to prevent confusion:

  • The Foreign Data Wrapper infrastructure, a mechanism to manage the definition of remote connections, servers, and users, is available in all supported PostgreSQL versions
  • The PostgreSQL Foreign Data Wrapper is a specific contrib extension that uses the Foreign Data Wrapper infrastructure to connect to remote PostgreSQL servers.

In particular, the Foreign Data Wrapper infrastructure will be used to manage definitions in both cases, that is, when using the PostgreSQL Foreign Data Wrapper and when using the dblink module.

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