Detailed Description

Cache invalidator iterators we need to apply, but cannot yet due to outer joins.

As soon as “table_index_to_invalidate” is visible in our current join nest (which means there could no longer be NULL-complemented rows we could forget), we can and must output this invalidator and remove it from the array.
