[ shrug... ] I don't see any meaningful differences between those numbers --- they're within 3% or so across versions, which is less than the margin of error considering I wasn't trying to control for outside effects like CPU speed stepping. Microbenchmarks like this one are notoriously noisy. Maybe there's some real difference there, but these numbers aren't to be trusted that much. What I was looking for was some evidence matching Laurent's report of the exception-recovery path being 500X slower than non-exception. That would have been obvious even with the sloppiest of measurements ... but I'm not seeing it. regards, tom lane
