> I hope this is promising. I've reviewed this and thought about it over some time. At first I was unhappy that you'd removed the restriction that timelines only change on a shutdown checkpoint. But the reality is timelines change at any point in the WAL stream - the only way to tell between end of WAL and a timeline change is by looking for later timelines. The rest of the logic seems OK, but its a big thing we're doing here and so it will take longer yet. Putting all the theory into comments in code would certainly help here. I don't have much else to say on this right now. I'm not committing anything on this now since I'm about to go on holiday, but I'll be looking at this when I get back. For now, I'm going to mark this as Returned With Feedback, but please don't be discouraged by that. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, 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
