If my opinion wasn't clear, I was suggesting adding a WARNING and not doing
anything about flattening. I can't say that, in 5 years of developing
applications in Postgres, that this has ever been a problem for me personally
-- from my perspective the persons reporting the issue needs to re-code their
query, it's not what sequences were meant for.
