Hi all,

Using "DELETE ... RETURNING *" against a remote partitioned table (parent) returns wrong results according attached test case.

I've tested it against all supported versions and got error just in 9.3, 9.4 and 9.5 version.

Attached ziped test case and results:
- fdw_test.sql (main test case script)
- fdw_test.expected.out (expected output)
- fdw_test.result-*.out (wrong results)

Some environment details:
