Found the reference: http://archives.postgresql.org/pgsql-hackers/2009-08/msg00078.php This was the email which I thought confirmed that the changes were worth it, even in the absence of benchmarks showing performance improvement. I guess the counter-argument is that so far this has been framed as a performance patch, and I've seen posts before which say that we don't accept those without benchmarks to show an actual performance improvement. Accepting it on the basis of evidence and comments so far would, I suppose, put it more in the category of a refactoring for cleaner code. Should we leave it to the code committer to make the final call? -Kevin
