Fix interaction of partitioned tables with BulkInsertState.
When copying into a partitioned table, the target heap may change from
one tuple to next. We must ask ReadBufferBI() to get a new buffer
every time such change occurs. To do that, use new function
ReleaseBulkInsertStatePin(). This fixes the bug that tuples ended up
being inserted into the wrong partition, which occurred exactly
because the wrong buffer was used.
Amit Langote, per a suggestion from Robert Haas. Some cosmetic
adjustments by me.
