Hi, hackers,
Attached is a patch that adds postgresql_fdw, FDW which retrieves
tuples from external PostgreSQL server, as a contrib module. This
patch is based on "SQL/MED core functionality" patch.
[SQL/MED - core functionality]
http://archives.postgresql.org/pgsql-hackers/2010-11/msg01698.php
Postgresql_fdw can be installed with the steps similar to other
contrib modules, and you can create FDW with the script:
$SHAREDIR/contrib/postgresql_fdw.sql
Note that you need to create postgresql_fdw for each database.
Document for postgresql_fdw is included in the patch, although the
contents might not be enough.
Any comments and questions are welcome.
Regards,
