The following line was added to the regression tests:
aggregates.sql:226:
select max(unique2), generate_series(1,3) as g from tenk1 order by g
desc;
I have no argument with what you say above. But one of my colleagues at
Truviso was doing some experiments, and it was causing a regression
failure here. I should have been more clear.
So if it truly is a useless query, shouldn't we at least remove the
regression test?
