Hi, I came across the patch since it was marked as "Needs review" (and then I realized that I mistakenly opened the upcoming commit fest, not the current one...).

I tested the patch and it LGTM too. I don't have a strong opinion on whether we should bother with a comment or not. As a side note I wonder whether we shouldn't assume that query_buf is always properly initialized elsewhere. But this is probably out of scope of this particular discussion. -- Best regards, Aleksander Alekseev
