Hi,
Of course, the geqo_threshold can be changed so that the geqo be performed
in queries that have less than 12 tables. However, we aim to test the GEQO
algorithm in conditions where the standard algorithm (dynamic programming)
has a high cost to calculate the query plan.

t method to conduct the tests? I take into consideration
the average of 10 executions or just the first one?
Do you think I must clean the cache after each query? (because the other (9)
executions may have information in memory).
