For the benefit of anyone searching the archives for the problem we
just hit, this message also occurs in 8.3.1 and also occurs against
the above test table for this statement:
test=# select max(j) as "maxj" from t1 order by "maxj";
ERROR: could not find pathkey item to sort
Neither statement causes the error when run against a build from
REL8_3_STABLE from 35 minutes ago (2008-04-22 10:15 CDT).
