Does "correlation" mislead the optimizer on large tables?


I don't know about large tables, but this is a big problem and
something I'm going to spend some time validating later today.  I
think Manfred's patch is pretty good and certainly better than where
we are but I haven't used it yet to see if it's the magic ticket for
many of these index problems.


I had to dig through a lot of archives to find this. Is this the patch, from last October?

If so, I'll try it out and report my results.
