Enhancement

We will record the live updates of the column size during DML(INSERT/DELETE/UPDATE/LOAD DATA, etc.).
It's inaccurate and may cause the column size to be negative. Also, it will hurt the performance when the table num is large.

So we'd better remove its maintenance. Let the column size only updated by ANALYZE.
