Because there wasn't any reasonable way to make them reproducible.
The set of things we can test in the regression tests is only a small
fraction of the interesting properties of Postgres. This is
unfortunate but ranting about "standard practice" doesn't change it.

It was done and we fixed a couple of bugs based on it (the one I can
think of offhand had to do with semantics of aggregate functions in
sub-selects). I don't think there's anything more to be learned there.
