Foreign Data Wrappers

In 2003, a new extension called SQL/MED ( "SQL Management of External Data" ) was added to the SQL standard. It is a standardized way of handling access to remote objects in SQL databases. In 2011, PostgreSQL 9.1 was released with a great support of this standard.

In a nutshell, you can now use various Foreign Data Wrappers (FDW) to connect a PostgreSQL Server to remote data stores. This page is an incomplete list of the Wrappers available right now. Another fdw list can be found at the PGXN website : http://pgxn.org/tag/fdw/

Please keep in mind that most of these wrappers are not officially supported by the PostgreSQL Global Development Group (PGDG) and that some of these projects are still in Beta version. Use Carefully !
