There's one slot for each batched tuple (they are reused). Before
materialization the tuples solely exist in tts_isnull/values into which
NextCopyFrom() directly parses the values. Tuples never get extracted
from the slot in copy.c itself anymore, table_multi_insert() accepts
slots. Not quite sure whether I've answered your question?
