已经把oltp.lua改掉了，支持10条SQL，(有需要可以再自行调整)包括
但是由于sysbench不能识别execute语句，所以都算成了other query， 实际上就是这些使用了服务端绑定变量的query。
在一台普通的X86机器上测试了一下，15GB数据，跑以下SQL能达到47万QPS。
-- select c from tbl where id = $1;
-- select id,k,c,pad from tbl where id in ($1,...$n);
-- select c from tbl where id between $1 and $2;
-- select sum(k) from tbl where id between $1 and $2;
-- select c from tbl where id between $1 and $2 order by c;
-- select distinct c from tbl where id between $1 and $2 order by c;
-- update tbl set k=k+1 where id = $1;
-- update tbl set c=$2 where id = $1;
-- delete from tbl where id = $1;
-- insert into tbl(id, k, c, pad) values ($1,$2,$3,$4);oltp_pg.lua源码
