In patches 0002-0004, they must avoid the multi insert path when there
are before-row triggers, instead-of-row triggers, or volatile functions
used (see copyfrom.c:917-1006).

Also, until we decide on the RETURNING clause, we should block the
multi-insert path for that, as well, or implement it by using the
callback to copy tuples into the caller's context.

In 0003, why do you need the global insert_modify_buffer_flush_context?

0004 is the only place that calls table_modify_buffer_flush(). Is that
really necessary, or is automatic flushing enough?
