Thanks.  I looked at:

https://www.postgresql.org/message-id/attachment/65997/v4-0001-TAP-test-for-copy-truncation-optimization.patch

and I now get it.  Adding a TAP test to src/test/recovery might make
sense, but I'm not completely sure.  In this case, we don't really want to
see if the WAL-skipping optimization works correctly but that it's
correctly *disabled* for foreign tables.

Thanks,
Amit
