I also would like to believe that the hit is small, but when PG official document writes "noticeable performance penalty", it becomes difficult to convince management that the hit is small :-)
Why ask us questions if you won't believe our answers?
Noticeable means it probably isn't important for most real-world cases, but if you work at it you can probably detect it.
