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).
