----------------------------- Log Message -----------------------------
Tweak recognition of range-clause pairs so that 'var > $1 AND var < $2'
(ie, parameters instead of consts) will be treated as a range query.
We do not know the actual selectivities involved, but it seems like
a good idea to use a smaller estimate than we would use for two unrelated
inequalities.
