Unfortunately, we might still need a manual parameter for override because of the interaction between wal_buffers and synchronous_commit=off, since it sets the max size of the unflushed data buffer. Discuss? And the "auto" setting should be -1, not 0kB. We use -1 for "use default" for several other GUCs. Other than that, I think Greg's numbers are fine, and strongly support having one less thing to tune. -- -- Josh Berkus PostgreSQL Experts Inc. http://www.pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
