* [PATCH 2/3] No multi-insert and bulk-insert when COPYing into partitioned tables

We might consider alleviating this restriction by allocating a
BulkInsertState object and managing tuple-buffering per partition.

* [PATCH 2/3] No multi-insert and bulk-insert when COPYing into partitioned tables

We might consider alleviating this restriction by allocating a
BulkInsertState object and managing tuple-buffering per partition.
