This GUC allows limiting the time spent waiting to acquire any one heavyweight lock. In support of this, improve the recently-added timeout infrastructure to permit efficiently enabling or disabling multiple timeouts at once. That reduces the performance hit from turning on lock_timeout, though it's still not zero. Zoltán Böszörményi, reviewed by Tom Lane, Stephen Frost, and Hari Babu |
