No, you're missing one factor in the spec. Timekeeper_1 for case_id = 182738
is not the same timekeeper as Timekeeper_1 for case_id = 217437. That's why
traditional crosstab plans don't work.
Anyway, here's the wrap-up: I tried Stephan's idea, it works, but it's so
slow that we're going to to the procedural loop. Thanks, all!
