It'll also potentially make it harder to get reproducible results in benchmarking and testing across repeated runs, cause confusion when someone relocates a DB or changes hardware, and slow down initdb (and thus testing). I'd be all for making it part of a "test my hardware and tune my DB" tool, but not such a fan of doing it at initdb time. Making initdb less predictable and more complicated sounds like asking for trouble. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
