It isn't clear what problem you are trying to solve. The write buffers and WAL are global across the cluster (group of databases), they're not per-database. So you can't really flush just one database as far as I know. You shouldn't generally need to do any kind of explicit flushing anyway. That's why a commit fsync()s. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
