My guess here, without looking, is that this was based on the idea of "oops, we're late here for the checkpoint, let's do as less work as possible to avoid getting even later", and thus skip some "unnecessary" tasks. I would vote for fixing this (and the SIGHUP issue too). I'm not sure how bad a behavioral change this is; IMO these fixes should be backpatched all the way back. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
