hi guys , Richad
you are right!, my apologies

yes i think is to truncate result size on the client
side , one message is send to user.
Comment 6 - Do you know about the genetic query
> optimiser and thq
> geqo_xxx configuration settings?
question about this ,my posgresl.conf is
# - Genetic Query Optimizer -
#geqo = true
#geqo_threshold = 11
#geqo_effort = 1
#geqo_generations = 0
#geqo_pool_size = 0 # default based on
tables in statement,
# range 128-1024
#geqo_selection_bias = 2.0 # range 1.5-2.0
is 11 join tables the threshold for activate Genetic
Query Optimizer?
