Except that Opensolaris and FreeBSD still have the old memory allocation behavior, as do older Linux kernels, many of which will remain in production for years. I have no idea what Windows' memory management behavior is. So this is a case of needing to know considerably more than the available RAM to determine a good setting. -- Josh Berkus PostgreSQL Experts Inc. http://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
