It doesn't change the current heap insert behavior so it's safe for the existing heap access method. But new table access methods could redefine this (only for tables created with these am's) and make index inserts independently of ExecInsertIndexTuples inside their own implementations of tuple_insert/tuple_multi_insert methods.

Changed as you proposed.

Done.

Also, I removed extra includes in 0001 as you proposed and edited the
commit message in 0002.

I'm going to push 0001, 0002 and 0006 if no objections.
