Review Comment:
Yes, I didn't fully complete the pull request yet. Currently, the
implementation is converting the table factors into a scan that are then
combined into a join; the extra flag columns are used to perform matching
later on when branching for the INSERTs, UPDATEs, and DELETEs. Do you think
just passing along a Scan instead of fully converting into a join would be
better?
