Hi, Just to be curious, why is wal_writer_delay limited to 10s? I am using postgresql in an embedded environment where every 10s sensor values are logged and even with "synchronous_commit = off" and wal_writer_delay=10000 this burns quite a lot of nand cycles. For me it wouldn't hurt loosing minutes of data - it is only important that the database is in a consistent state after power loss. Thanks, Clemens PS: It is really impressive how flexible and powerful postgresql is. I am using it on small TP-Link OpenWRT router (32m ram, 400mhz MIPS), on a raspberry pi as well as on larger servers for "real" database stuff with huge Hibernate-generated queries. Whenever/weherever I use postgresql, it does an excellent job and is rock-solid. Thanks a lot for this impressive piece of work :) -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
