Yes, we must accumulate results because the aligned format needs to know the columns widths for a entire "page", and the row-by-row logic does not fit that well in that case. One of the posted patches implemented this with an array of PGresult in single-row mode [1] but I'm confident that the newer version you pushed with the libpq changes is a better approach. > So I whacked the patch around till I liked it better, and pushed it. Thanks for taking care of this!
