Do you mean that the new message_level_is_interesting() call isn't
noticeable? Or that the extra work to build the StringInfo can't be
noticed in an unpatched version? If it's the latter, then what's the
point?
Your opening email seems to indicate that you noticed the issue from
looking at the code. So, it appears that you didn't do this because
you noticed that there was an actual measurable overhead and you saw a
way to fix it. If that's the case then perhaps you've just assumed
this will make a meaningful difference. If I've misunderstood that,
please correct me and show us your test cases and the performance
results.
