Hi Adam, Milan,

Milan says,

>>Why don't you use 1.5.3?
>>Many bugs are fixed since 1.5.0.

Some consumers don't want to upgrade software. They have an image that
upgrage solve some defects(or bugs) and bring some defects at the same time.

Adam, thank you for your information in detail.
I made a SQL to avoid using redundant indexes. It become fast.
I try to investigate why optimizer determine to use redundant indexes.
