Log message:
    Fix range-query estimation to not double-exclude NULLs, per gripe from
    Ray Ontko 28-June-02.  Also, fix prefix_selectivity for NAME lefthand
    variables (it was bogusly assuming binary compatibility), and adjust
    make_greater_string() to not call pg_mbcliplen() with invalid multibyte
    data (this last per bug report that I can't find at the moment, but it
    was in July '02).
