OK. That's another matter entirely.   Who should make that decision? Is
there a committee or a person who would be capable of making that decision?

So, I will have to go back on my decision to use Postgres and
re-consider MySQL? I will rather throw away the effort invested in
studying Postgres than to risk an unfixable application downtime.  I am
not sure about the world domination thing, though. Optimizer hints are a
big feature that everybody else has and Postgres does not have because
of religious reasons.
