Hmmm,isn't there old transaction running somewhere ?
If so,this may be due to the use of SnapshotNow in CREATE INDEX
command which Tom already specified a few months ago.
We have already SnapshotAny(Jan added ?) now.
Probably this would be solved by changing SnapshotNow -> SnapshotAny.

Seems this is also related to the potential vacuum bug Tom pointed out
about handling of HEAP_MOVED_IN(OFF) flag. I'm suspicious about
the following stuff. I think HEAP_MIN_INVALID tuples should always
* If tuple is recently deleted then we must
* from relation.
if (tupgone && tuple.t_data->t_xmax >=
tupgone = false;
