It might be nicer to express this as "up to n MB of WAL per second", but otherwise seems reasonable, and it's easy enough to convert WAL MB/s into a delay by hand. Initial tests of this show that it does limit index creation rates as expected, while continuing to allow WAL generation at normal rates for other concurrent work. -- 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
