Hmm, I recall this technique being used elsewhere and is sometimes useful. Can't remember where though -- by manpages, it's not rsync nor pv ... How about making it a toggle? Default off, enable-able by option, toggleable by signal. (If you enable it via the signal, what's the rate to report at?) -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
