The other one you mention has a detailed comment above it explaining why it should be 2.0 rather than 1.0, so I left it. Let me know if you still think it should be removed? I can see the argument both ways. Or maybe we need another patch to account for manual checkpoints. -- Simon Riggs 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
