In the scenario we studied, the truncations were causing periodic hiccups which were quite severe. The truncations were completely useless anyway because the table grew back to the original size daily (a few dozen GBs I think). That was a lot of unnecessary work, and under exclusive lock no less. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
