Thanks Kevin, we made the changes for query performance reasons. Our schema is such that the changes above make enough
ofan impact to make it worthwhile.
I think we're now looking at a two-phase validation process; an initial regression test on any new version we take then
afurther check using our settings. I guess it's actually more useful that we must now inspect the results since it
mighthelp us to squeeze even more performance boosts out of Postgresql.
All the best, John
