#3966 is implementing the same functionality (and more) but the author has lost interest and I don't have the knowledge to take over the unnest parts of his PR, I felt my solution to multiple joins is simple enough the other functionality could be rebased on top of it assuming a new owner takes it on.

This looks good to me. Would you mind adding a test case for LEFT JOIN as well, just to be sure we don't add any regressions in the future?

nit: Could we also add a LEFT JOIN test here? I've verified that it does work, but adding a test case could prevent potential regressions in the future.
