Hi Bruce. Some of the "order by" clauses are currently broken in the
regression tests (at least on my machine). Do you see this also? For
example, in the point test:

QUERY: SET geqo TO 'off';
QUERY: SELECT '' AS thirtysix, p1.f1 AS point1, p2.f1 AS point2, p1.f1 <->
p2.f1 AS dist
FROM POINT_TBL p1, POINT_TBL p2
ORDER BY dist, point1 using <<, point2 using <<;
thirtysix|point1 |point2 | dist
---------+----------+----------+----------------
|(0,0) |(-10,0) | 10
|(-10,0) |(-10,0) | 0
|(-3,4) |(-10,0) |8.06225774829855
...

Also, some of Vadim's contrib stuff is broken since WARN is no longer
defined. I can post patches for that (there are two files affected) but
substituted ERROR and am not certain whether that is the correct choice.

Let me know if I can help with anything...
