So I wrote some comments but wasn't going to repost the patch with the unchanged name without explanation... But I think you're right though I was looking at it the other way around. I want to have an API for a two-stage sync and of course if I do that I'll comment it to explain that clearly. The gist of the comments was that the function is preparing to fsync to initiate the i/o early and allow the later fsync to fast -- but also at the same time have the beneficial side-effect of avoiding cache poisoning. It's not clear that the two are necessarily linked though. Perhaps we need two separate apis, though it'll be hard to keep them separate on all platforms. -- greg -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
