Absolutely, +1 on this. In Greenplum we print the runtime of the script and the runtime of the diff, both of which have provided useful feedback on where to best spend optimization efforts (the diff time of course being a lot less interesting in upstream postgres due to gpdb having it’s own diff tool to handle segment variability). cheers ./daniel
