PostgreSQL does not support this feature at this time. And, I would not expect it any time soon. You would have to either code such a join by hand. There is one other option. Many ODBC compliant tools will support multi-data source joins. However this solution may perform poorly because one side of the join may iteratively query one of the data sources. Your call.
