beb22d086b Minor tweaks to query planning weights so that when STAT4 is enabled 
and functioning, a full table scan is more likely to be selected if
that seems like the fastest solution.  Only do this when STAT4 info
is available because an error has a large potential downside.

403869680b Sometimes it makes sense to do a full table scan rather than try to use

tune the query planner to make that happen more often.
