I know Tom would like a definitive and thorough testing to determine the
proper GEQO threshold limit , and that is the right thing to do, of course.
But just as a quick notice to those upgrading from 7.3 to 7.4 with fully
normalized databases requiring > 11 joins, the GEQO setting can be a
killer...
How about a TIP:
"For large number of joins, test whether the GEQO settings are right for
you"
