Tom, that was a very unhelpful reply. I don't have the luxury of
reading, much less remembering, every thread that has occurred on
the hackers mailing list. Perhaps you mean the discussion from
July 6, 2009 started by Robert Haas? That was approximately 8000
messages ago, and no consensus was reached that I could find. So
I'd like to respectfully ask the hackers to consider raising the
default value from 12 to 16 (as Robert Haas first suggested) or
even higher (20?). Whether or not we make GEQO less random, replace
it someday with something else, tweak *_collapse_limit, etc. is not
as important in my mind as minimizing this unexpected foot gun for
future releases. Thanks.
