Yeah, backporting GUCs is not a big deal. Sure, the GUC won't appear in postgresql.conf files generated by initdb prior to the release that introduces it. But users that need it can just edit their .confs and add the appropriate line, or just do ALTER SYSTEM after the minor upgrade. For people that don't need it, it would have a reasonable default (probably work_mem, so that behavior doesn't change on the minor upgrade). -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
