Re: full-scan vs index for "small" tables

Sheesh, people are really keen on bagging the CBO...Hell, we all know
its trivial to produce scenarios where the CBO will get it wrong
(inter-column dependencies always being a common one)..

But a little humility please...I've also had many times where I've
seen a plan and thought..."Nah, CBO has got it wrong"...so I hint it
in the way that I think will be best, and guess what, my option sucks
and the CBO's choice was better...Man, we all stay quiet on that one
don't we...
