Alexander Korotkov d1d286d83c Revert: Remove useless self-joins ... This commit reverts d3d55ce571 and subsequent fixes 2b26a69455, 93c85db3b5, b44a1708ab, b7f315c9d7, 8a8ed916f7, b5fb6736ed, 0a93f803f4, e0477837ce, a7928a57b9, 5ef34a8fc3, 30b4955a46, 8c441c0827, 028b15405b, fe093994db, 489072ab7a, and 466979ef03. We are quite late in the release cycle and new bugs continue to appear. Even though we have fixes for all known bugs, there is a risk of throwing many bugs to end users. The plan for self-join elimination would be to do more review and testing, then re-commit in the early v18 cycle.
