I have just fixed many of these WARN problems.  I am looking at the new
results.  The first problem:

    ======   boolean   ======
    166,168d165
    <           |f |f
    <           |f |f
    <           |f |f
    170a168
    >           |f |f
    173a172
    >           |f |f
    176a176
    >           |f |f

is because the query has no ORDER BY.

The second problem looks serious:

QUERY: SET geqo TO 'off';
QUERY: SELECT '' AS thirtysix, p1.f1 AS point1, p2.f1 AS point2, p1.f1<-> p2.f$
   FROM POINT_TBL p1, POINT_TBL p2
   ORDER BY dist, point1 using <<, point2 using <<;
thirtysix|point1    |point2    |            dist
---------+----------+----------+----------------
         |(10,10)   |(-10,0)   |22.3606797749979
         |(0,0)     |(-10,0)   |              10

The 'dist' is not being ordered.

In geometry we have:

104c103
    <       |(0,0)     |[(0,0),(6,6)]                |(-0,0)
    ---
    >       |(0,0)     |[(0,0),(6,6)]                |(0,0)

I am happy to see the -0 changed to zero, but this may be just on my
platform.  Also:

    <           |(-0,0),(-20,-20)
    ---
    >           |(0,0),(-20,-20)
    213c212
    <           |(-0,2),(-14,0)
    ---
    >           |(0,2),(-14,0)
    221c220
    <           |(14,-0),(0,-34)
    ---
    >           |(14,0),(0,-34)
    236c235

We also have broken sorting in timespan:

QUERY: SELECT '' AS fortyfive, r1.*, r2.*
   FROM TIMESPAN_TBL r1, TIMESPAN_TBL r2
   WHERE r1.f1 > r2.f1
   ORDER BY r1.f1, r2.f1;
fortyfive|f1                           |f1
---------+-----------------------------+-----------------------------
         |@ 6 years                    |@ 14 secs ago
         |@ 5 mons                     |@ 14 secs ago
         |@ 5 mons 12 hours            |@ 14 secs ago

How long has this been broken?  Any idea on a cause.  Obviously it is a
sorting issue, but where?
