Doing my routine patching seems to have exploded my mail server,
sorry for not replying sooner!

I don't actually have planning vs. execution time statistics from
the older version for the queries in question -- there were not 'problem
queries' and therefore were never really analyzed. My customer's already
dragging me off to another issue, so I've got to shift gears.

Appreciate all your work -- thanks again!!! :)
