Hmm, even by default (without specifying prepareThreshold), it seems
that the planner looks at the parameter values for the first execution
of the query. (See my post a couple minutes ago*). Am I mistaken?
If I'm not mistaken, then for one-shot queries, is there any any
additional advantage to setting prepareThreshold to 0?
BTW, is the default value of prepareThreshold is 1?
Thanks,
