You mean the bistate member of CopyMultiInsertBuffer?
We do not use that member at all for foreign tables, so the patch
avoids initializing that member in CopyMultiInsertBufferInit() when
called for a foreign table. So we have bistate = NULL for foreign
tables (and bistate != NULL for plain tables), as you mentioned above.
I think it is a good idea to add such assertions. How about adding
them to CopyMultiInsertBufferFlush() and
CopyMultiInsertBufferCleanup() like the attached? In the attached I
updated comments a bit further as well.
Thanks for reviewing!
