SAS=2M, CACHING=50, ADJ=10.
My HASH was 10M, then dropped it down
all the way to 260K, at which stage it
threw out the MERGE JOIN CARTESIAN and went back
to HASH JOIN only. So I threw it out completely
(default 0), which would have made it 2M given
that SAS dependency. But the MERGE JOIN CARTESIAN
did disappear with HASH defaulted, even though it was
there while I tried HASH 2M! More mystery...
So far, Anjo Kolk has provided me with the most plausible
explanation and it has nothing to do with any of
these parameters...
